as 100 milliliters of 0.10 molar KOH is added to 100 milliliters of 0.10 molar HCL at 298 K, the pH of the res?A. decrease to 3B

Mila [183]

Answer:

C. increase to 7.

Explanation:

Hello,

In this case, the undergoing chemical reaction is:

$KOH+HCl\rightarrow KCl+H_2O$

Thus, the molar relationship is 1 to 1, therefore, the moles are:

$n_{HCl}=0.1mol/L*0.1L=0.01molHCl\\n_{KOH}=0.1mol/L*0.1L=0.01molKOH\\$

Thus, since the entire hydrogen ions are neutralized, the pH C. increase to 7.

Best regards.
