Water Equilibrium Experiment

Effect of Acids and Bases on Water Equilibrium:
If an acid (H+) is added to the water, the equilibrium shifts to the left and the OH- ion concentration decreases.
Water Equilibrium: H2O ↔ H+ + OH-
If base (OH-) is added to water, the equilibrium shifts to left and the H+ concentration decreases.
Water Equilibrium Principle: The multiplication product (addition of exponents) of H+ and OH- ion concentration must always be equal to 10-14.
BOTH H+ and OH- ions are ALWAYS PRESENT in any solution. A solution is acidic if the H+ are in excess. A solution is basic, if the OH- ions are in excess.
Definition of pH, pOH, and pKw:
The concentrations of hydrogen ions and indirectly hydroxide ions are given by a pH number. pH is defined as the negative logarithm

The limitation with this indicator is that it is not specific in other words it’s not accurate.
Electronic pH meter: It is a machine that measures the concentration of hydrogen ions in the solution. It gives a pH value up to two decimal places, which makes it an accurate method to use while finding the pH value. The only drawback with this method is that it could be expensive.
Titration: Titration is another method that determines the concentration of a solution. It is a cheap and accurate way to find the pH of soft drinks. Titration is a procedure that involves the slow addition of one solution of a known concentration called a titrant to a know volume of another solution of unknown concentration until the point where the solution reaches neutralization. This is often indicated by a color change.
For the experiment that I am conducting the method that I’m going to employ is titration as it is one of the most cheap and accurate way to find the pH of soft drinks. While conducting the experiment an electronic pH meter and a pH indicator paper would be used to check and verify that the values are
