Question

Water has a pH of 7. If you add and acid to this water, how would it affect the pH?

)
A)
pH would increase
B)
pH would decrease
pH would not change
D)
All of The Above

Answer 1

B, PH would decrease

Answer 2

pH would decrease in this case

Step-by-step explanation:

Adding water to an acid or base will change its pH. Water is mostly water molecules so adding water to an acid or base reduces the concentration of ions in the solution. When an acidic solution is diluted with water the concentration of H + ions decreases and the pH of the solution increases towards 7.
