Colorimeter And Labquest: A Case Study
First, a colorimeter and LabQuest were retrieved and and plugged in to warm up. While the colorimeter and LabQuest was warming up, 3 test tubes were labeled 1,2, and 3. Then, the control pH 7 solution was made according to Table 1 right in the corresponding test tubes. The test tubes were then immediately placed in a 100mL beaker with an ice cube in it to keep the solutions cold. The solution in test tube 1 was poured into a cuvette that was labeled with a piece of tape on the cap that said “B”. After the solution was poured in, the sides of the cuvette were wiped off with a Kimwipe to get rid of any fingerprints that could affect the colorimeter reading. The colorimeter was then set to the 470 nm setting, and then the “B” cuvette was
Procion Red Dye Lab Report
1454 Words | 6 PagesFor this lab, zeolite and magnetized zeolite were synthesized and compared with charcoal to find out with would be the most effective in the sequestering of Procion Red dye. Finding the concentration and absorbance of each zeolite, magnetized zeolite, and charcoal, along with a calibration curve, the best adsorbent is determined. Charcoal was the overall best sequestration of the Procion Red dye, since the adsorbent was highest compared to the others. Introduction Pollution has increased in the environment over the years, so the purpose of this experiment is to find the best adsorbent of chemicals to reduce the pollution.
Tube B Biology Lab Report
431 Words | 2 PagesIn Tube A with the water snail, cellular respiration is being undergone. Tube B, is a aquatic plant so, for this tube, photosynthesis is most likely happening. Tube C has both the water snail, and the aquatic plant which means there is going to be an equilibrium of both processes being the photosynthesis, and cellular respiration. Tube D is the control. BTB or bromthymol blue is a solution used to detect changes in pH. The detection of pH is associated with the amount of CO2 present, meaning that the pH changes with the amount of CO2.
Quantitative Spectroscope And Visible Light Lab Report

Brønsted-Lowry Acid Base Theory
861 Words | 4 PagesWith a measure pH of 11.93, calculated pH of 12.8, and a percent error of 7.29%, the results depict experimental errors. Unlike the unbuffered solutions, the buffered solutions are all accurate, with each solution containing a percent error less than 5.0%. This may be due to the fact that solving for buffer solutions is faster, requires less crunching of numbers, and therefore less opportunities for mistakes to

Gunshot Residue (GSR) Evidence
1559 Words | 7 PagesOn the orange ring 5% sodium rhodizonate is added. Red color formation shows the presence of Barium (Ba) and Lead (Pb). On the red color spot HCL is added after drying the swab. If it turns into blue, it confirms the Lead and no change in color confirms the Barium.
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.
Cuvette Enzyme Lab
1834 Words | 8 PagesThen, the cuvette that labeled #1 was wiped off with the KimWipe and placed in the single cuvette holder in position 1 in the sample compartment. The position 1 was making sure aligned with the light source. The sample compartment door was closed, and was pressed “auto zero” button on the keypad. Then, after 30 seconds, the absorbance that displayed on the screen was read again and it was 0. The absorbance was read at 0 seconds, at 30 seconds, at 60 seconds, at 90 seconds and at 120 seconds.
Colorimeter Lab Report
1015 Words | 5 PagesColorimetric method –instrument and application Introduction: - Colorimeter is device which is used to measure transmittance and absorbance of light passing through a liquid sample. It is a light sensitive device. Principle: - Colorimeter works on the principle of Beer-Lambert’s Law. Beer-Lambert’s Law states that when visible light from a natural or artificial source falls on a colored homogenous medium contained in a glass container, the color of the medium is the complementary color of the light that has been absorbed by the medium.

After 5minutes, the boiling tub, labelled A, was withdrawn from the water bath. 4) The sample was filtered using a Buchner funnel, collected in a sample vile, labelled A, and positioned securely to dry and crystallise in an oven at 65°C. 5) After 45minutes, the boiling tube, labelled
Calcium Carbonate (Caco3) Content In Toothpaste By
2190 Words | 9 PagesSynopsis This experiment is the determination of Calcium Carbonate (CaCO3) content in toothpaste with the use of back titration while demonstrating quantitative transfer of solids and liquids. A accurately weighed quantity of toothpaste was dissolved in excess volumes of HCl. This solution is then titrated with NaOH to find the volume of the excess HCl. The volume of HCl reacted, which is found by substracting the volume of given HCl with the volume of excess HCl reacted, can be further manipulated with mole fractions to find the mass of CaCO3 and thus the CaCO3 content in toothpastes.
Colour And Temperature Experiment
2992 Words | 12 Pages3. Introduction: This experiment was performed to determine whether colour has an influence on a person’s mood, blood pressure and pulse rate. People attach different meanings to different colours that may influence their emotions, blood pressure and pulse rate. Different coloured lights; blue, green, red, yellow and white (neutral) were used in a dark room and the participant’s blood pressure and pulse rate was monitored and recorded on an observation sheet to determine if colour has an influence on these variables.
Colorimetric Analysis Lab Report
818 Words | 4 PagesOBJECTIVE The objective of this experiment was to analyze and determine the unknown concentration of a protein solution by utilizing two different colorimetric techniques; Biuret and Lowry. The Biuret method was used with unknown #2 and the Lowery method was used for unknown #1. After the concentration of each unknown was analyzed (by Biuret or Lowry method), the alternate objective was to compare the results achieved by each method and to determine if the results from the approaches were consistent in contrast to each other. THEORY Biuret and Lowry methods use colorimetry as a tool to analyze protein concentration quantitatively.
