Yes it does. pH is defined as the -log of the concentration of hydrogen ions in a solution, or -log[H+]. As you add water to an acid, you are diluting it, thus lowering the concentration of H+. Putting a lower value in for [H+] in the equation -log[H+] will give you a great value than you originally had. This means the pH has increased, making the solution more basic.
Adding water to an acid can dilute the solution, potentially lowering the concentration of hydrogen ions (H+) and thus increasing the pH. However, the pH change may not be significant depending on the initial concentration of the acid and the amount of water added.
water is amphoteric in nature with acid it behaves like base and with base it behaves like acid.
when water is added to the acid it behaves like a base and neutralises it to some extent and thus the pH of acid decreases on adding water.
Answer 2:
When you add water to the acid, you are diluting it and making it weaker therefore the pH will decrease (the value will get closer to 7 on a pH scale).
The whole point of a buffer is that when a little bit of acid or base is added, the pH does not change significantly.

What will neutralise pH 13.5?
Adding an acid the pH decrease.
Does adding water to a base make the pH higher or lower?
Adding water to a base will not change the pH of the solution, but it will dilute the base concentration. If you add water to a basic solution, the pH will remain the same, but the concentration of the base will decrease.
Does adding 1X PBS (phosphate buffered saline) change the pH of an acidic solution like HCl?
The pH of PBS is 7.4, which makes it slightly basic. 1M HCl solution has the pH of 1. While it's true that adding a base to an acid will change the pH of the acid, unless you use a very dilute sample of HCl and a very large sample of PBS you will need a very sensitive pH meter to see any pH change.
How does acid or base affect pH of distilled water?
Adding an acid to distilled water will lower the pH, making it more acidic. Conversely, adding a base to distilled water will raise the pH, making it more alkaline. pH measures the concentration of hydrogen ions in a solution, so adding acid increases these ions, while adding a base decreases them.
What are other ph decreasers?
Adding an acid to a solution can cause the ph to decrease. Looking at things in the molecular level a good acid or something that will be able to decrease the ph will be anything that can easily donate an H+ ion to a solution. Strong acids are examples
On addition of concentrated Hydro chloric acid to water does the pH of the acid change?
The pH of the hydrochloric acid does not change when it is added to water since it is already highly acidic. The concentration of the acid will remain the same, which means the pH will also remain constant.
Does water change the pH level of vinegar?
Yes, water can dilute vinegar and change its pH level slightly. Adding water to vinegar will decrease its acidity, thus raising the pH level. However, the change may be minimal depending on the amount of water added.
How do you reduce water pH?
Lower pH by adding muriatic acid.
What would be the pH of the water before adding an acid?
pH of water is 7.0 (meaning neutral)
How do you find the pH of a water after adding a strong acid?
either use pH paper or a pH meter
Does adding salt to fresh water in and of itself change the pH of the water?
The pH is unchanged.
Would adding distilled water increase the pH of an acid in solution?
yes, any water.
What does adding sulfuric acid to water do to pH?
Sulphuric acid will react with calcium hydroxide(lime water) to give calcium sulphate. Initially slightly white turbidity may be seen but then the turbidity dissolves and calcium sulphate solution is obtained. Heat is released and temperature of solution rises. Note - Lime water is saturated solution of calcium hydroxide.
Does the pH of ethanol change if water is added?
Yes, adding water to ethanol will change its pH. Ethanol is a neutral compound with a pH of around 7. However, adding water will dilute the ethanol, potentially changing its pH depending on the amount of water added and the initial concentration of the ethanol solution.
Does adding salt to freshwater aquariums change the Ph level of the water?
No
What does adding Carbon Dioxide do to the pH in water?
Adding carbon dioxide to water can lower the pH by forming carbonic acid through a reversible reaction. This reaction releases hydrogen ions, leading to an increase in acidity and a decrease in pH.
How do you change the pH of a water solution?
Add an acid or a base to it.
