Question

As the pH value of a neutral solution increases
(A) basic property decreases and number of OH-ions increases
(B)
acidic property increases and number of H+ ions decreases
(C)
basic property increases and number of OH ions increases
(D)
acidic property decreases and number of H* ions increases.​

Answer 1

A) basicity increases, OH⁻ ions increases. Hence, basic property increases and number of OH⁻ ions increases as pH value increases.

B) pH value ranges from 0 to 14. ... Increasing pH value towards basicity increases number of OH- or hydroxyl ions, which impart basicity to the solution. Decrease in pH towards 0 will increase hydrogen ions or H+ concentration, which will impart acidity to the the solution.

C) basicity increases, OH⁻ ions increases. Hence, basic property increases and number of OH⁻ ions increases as pH value increases.

D) Decrease in pH towards 0 will increase hydrogen ions or H+ concentration, which will impart acidity to the the solution.
