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.

When citric acid is added will the pH increase or decrease?

When citric acid is added, or any acid for that matter, the pH of a substance will decrease. This is because since acids have a low pH they will decrease the pH of other substances when added to it.

What happens to the buffer solution pH 7 when acid is added?

When acid is added to a buffer solution at pH 7, the pH of the buffer solution will decrease. However, due to the presence of a conjugate base in the buffer solution, the buffer will resist the change in pH and try to maintain its original pH value. This is because the conjugate base will react with the acid and prevent a significant decrease in pH.


How does an acid affect pH and H plus concentration when added to water?

It increases H+ concentration and decrease pH according to pH = -log[H+] If acid is strong (it doesn't have a Ka>1) it will be ionized 100%. If it's not >1 it will be ionized according its Ka. It's called weak and pH is not so strongly affected as if it were strong


When hydrochloric acid a strong acid is added to water the pH oh water is?

What can be used to decrease the pH of water?

Depending on the pH factor of the water now, you could add acid to decrease the alkaline factor.


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
