Question

question 31 (2 points) listen an acid is a compound that liberates ___ in solution, and causes the ph of that solution to ___. cl⁻, remain unchanged mg⁺⁺, remain unchanged h⁻, increase h⁺, decrease na⁺, increase

Explanation:

An acid is defined as a substance that donates hydrogen ions ($H^{+}$) in solution. The pH scale is based on the concentration of $H^{+}$ ions, where a higher concentration of $H^{+}$ ions leads to a lower pH value. When an acid donates $H^{+}$ ions in solution, the $H^{+}$ ion - concentration increases and the pH of the solution decreases.

Answer:

D. $H^{+}$, decrease
