Which statement is true for a solution when its concentration of hydronium ions increases? (5 points) aIt becomes less acidic. bIts pH value increases. cIts pH value decreases. dIt becomes more alkaline.

Respuesta :

Answer:

c. Its pH value decreases.

Explanation:

Remember that hydronium ions are represented by H3O (+), the concentration of this will be used in the concentration of protons H (+) and the formula of pH is the following:

[tex]pH=-log\lbrack H^+].[/tex]

If the concentration of H (+) increases, the pH will decrease. You can check this matematically. And when the concentration of H (+) decreases, the pH will increase. So the answer would be c. Its pH value decreases.
