Solubility Test Lab Report
Abstract The purpose of this lab was to identify the unknown and find out which solution is solubility. The test was done to determine the identity of the compound include solubility test, flame test, formation of precipitate and last PH test. It was found that the unknown compound smell like chorine, was soluble in water. The flame test matches the color of calcium chorine indicating that the unknown compound contained chorine, also the anion test sodium chorine proved to be positive. Resulting in the experiment that the unknown compound was chorine. Introduction As a groups to identify an unknown compound, we need to know its physical properties (color, state and smell). David brought all the compound that are need to for the project and …show more content…
It was found that the compound was solid and white in color. The unknown compound was then tested solubility in water and the compound was soluble in the water. The flame test was performed for four know compound calcium chorine, sodium chlorine and ammonium chorine and the unknown compound. When unknown compound was put on the fire different color are produce. When we smell the unknown compound it indicated the presence of chorine. 3MHNO3, 1ml of Agno3 and unknown compound formed precipitate. Conclusion After doing flame test, solubility test and PH test, the groups able to identify the unknown compound, after all of the tests and reactions were performed, it was found that the unknown compound was chlorine, it is solubility in the water. The flame test matches the color of calcium chorine indicating that the unknown compound contained chorine. We also used ice to see whether unknown compound will dissolve in the ice. We used 3ml of ice and 0.5 g of unknown and 1-gram sodium carbonate and 1g unknown carbonate in 10 ml H20. when we first mixed ice with unknown it melts then we used sodium carbonate and unknown carbonate it forms white precipitate. for the final test we used 1-gram sodium bicarbonate and unknown with 15 ml of H20 then it bubbles up. After we done with all other test, we like to see the PH of the sodium bicarbonate and unknown, its initial temperature is 20 and the final temperature was 24 and then PH paper turn blue and its has the PH of 8-9 and its very
Unknown Mixture Lab Report
302 Words | 2 PagesProcedures In this experiment, an unknown mixture was given, that contained both sodium bicarbonate(NaHCO3) and sodium chloride(NaCl). The purpose of this experiment was to find the percent (%) composition of the sodium bicarbonate and sodium chloride in the unknown mixture. Hydrochloric acid(HCl) and a scale were materials that were also used during the lab.

Experimental Design and Discussion of Results The objective of this experiment was to identify an unknown compound through quantitative and qualitative analysis. In order to find the identity of the unknown compound, an initial qualitative test for solubility was performed.
Unknown Compound
1270 Words | 6 PagesTo test for the presence of the ammonia cation, a scoop of the unknown compound was mixed with NaOH to see if the resulting solution had a noticeable smell that would affirm the presence of ammonia. A moist piece of pH paper was then held near the solution to see if the ammonium would dissolve the water on the pH paper. The next cation test performed was the flame test. A gram of the unknown compound was held by a metal stick above the flame of a Bunsen burner to see what color flame the compound would produce. The chart in the lab manual on page 63 was used to determine what cation correlated with what flame color.

For example, alka-seltzer helps with migraines, headaches, sinus headaches, muscle pain, and symptoms of pain. Alka-seltzer contains aspirin, sodium, hydrogen carbonate, citric acid, natural flavors, and artificial flavors. These are just some of the ingredients. When an alka-seltzer dissolves it releases all of the medicine.

The formation of o-nitroacetanilide is inevitable and in order to eliminate it, 95% ethanol is used as the solvent of choice. The ortho isomer is soluble in the cold alcohol solution whereas p-nitroacetanilide in insoluble. As a result, the ortho isomer remains in the liquid solution and the final product, the p-nitroacetanilide is isolated with a final vacuum

It was assumed that the remaining starting material was concentrated from a decrease volume to reappeared in solution. Nevertheless, this may have been a sign of contamination that will negatively affect the entire reaction. This observation later resulted in a yellowish

After that, we added HCl or stomach acid and both drugs dissolved and were soluble. We tested the pH and it dropped to 1.0. They both turned a brownish-yellow when the iron nitrate was added and no other pain reliever or antacid looked like those two.
Unknown B Test Lab Report
500 Words | 2 PagesWe identified unknown A as acetaminophen. This is because unknown A had all the same tested properties as acetaminophen when we performed our tests. For unknown B we found it to be acetaminophen and caffeine. This is because like unknown A, unknown B properties were the same as acetaminophen, but unknown B was acetone soluble. Unknown B has similar properties to caffeine because it was acetone soluble and because caffeine was the only basic pH tested to change color during the FeCl3 test.
Unknown White Compound Lab Report
1367 Words | 6 PagesAbstract: The purpose of this experiment was to identify given Unknown White Compound by conducting various test and learning how to use lab techniques. Tests that are used during this experiment were a flame test, ion test, pH test, and conductivity test. The results drawn from these tests confirmed the identity of the Unknown White Compound to be sodium acetate (NaC2H3O2) because there were no presence of ions and sodium has a strong persistent orange color. The compound then will be synthesized with the compounds Na2CO3 and HC2H3O2 to find percent yield.
Essay On Soda Water Titration
1337 Words | 6 PagesThe soda water will be stored in 5 different temperatures : 5℃, 15℃, 25℃, 35℃, and 45. The desired temperatures will be achieved by using the water bath and refrigerator. I chose phenolphthalein as the indicator, because it is commonly used for titration and is a weak acid. Phenolphthalein is usually used when the solution is strong base and weak acid. When it is added into an acidic solution, the solution will be colourless; when it is added into an alkaline solution, the solution will turn pink.

Then we were to classify each type of solid as either ionic, metallic, non-polar molecular, polar molecular, or network. Paraffin wax classified as a non-polar molecular, Silicon dioxide was classifies as a network, Sodium chloride was classified as ionic, Sucrose was classified as polar molecular and Tin was classified as metallic. (2)The intermolecular forces that are present in Paraffin wax are dispersion forces, because it is non-polar and carries a negative charge. Followed by Sucrose that has
