Question

Which of the following relationship is true for an acidic solution at 25°c

Answer 1

Answer:

The higher the concentration of OH- in a solution, the more basic the solution is. Pure water undergoes a reversible reaction in which both H+ and OH- are generated. The equilibrium constant for this reaction, called the water dissociation constant, Kw, is 1.01 × 10-14 at 25 °C.

Answer 2

Solution having H+ion conc. of 10 ⁻²M

: At 25 °C, a pH < 7 indicates an acidic solution, a pH > 7 a basic solution, and a pH = 7 a neutral solution.

pH=−log[H +]

C=2

pH<7 is acidic.

∴C is acidic
