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).

∙ 15y agoYes 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.

∙ 7y agoThe 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 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.
Does weak acid always act to change the pH when placed in water?
Not necessarily, if a solution of a strong acid is very dilute it will have a higher pH than some weak acids in higher concentrations.
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
What is the pH of a neutral liquid?
Nope, pH of water is neutral, but if you mix it with so;ething acid or basic, the whole pH of your solution will change Hydrochloric acid is sold in a 37% water solution (37g of HCL in 100g of water) Most part of it is water, but your pH is far from 7
On addition of concentrated Hydro chloric acid to water does the pH of the acid change?
Yes, pH depends both on the strength of the acid and the concentration. Adding the acid to water will dilute it, creating a solution with a higher pH.
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 water change the pH level of vinegar?
no. water just dilutes the acid but the PH will not change unless an acid or alkali is added
Does adding salt to fresh water in and of itself change the pH of the water?
The pH is unchanged.
Why would adding an acid or base lower the pH in a solution?
Adding an acid to a solution will lower it's Ph, but adding a base will raise it's Ph.
Would adding distilled water increase the pH of an acid in solution?
yes, any water.
Why does the pH of water decrease when a acid is added?
Acid on the PH scale is from 1 to 6. water being 7 and anything above seven to 14 being a base. Adding an acid with a ph of 1 with water makes it a 3.5 on the ph scale. How?, The acid's H+ or H3O- became less concentrated when water was added.
Does adding salt to freshwater aquariums change the Ph level of the water?
No
Does adding water change the pH of a base?
Yes. Ph is a measurement of the concentration of the hydronium ion [H+]. If you add more water you change the concentration.
What will neutralise pH 13.5?
Adding an acid the pH decrease.
