Answer:
pH = 5.2
Explanation:
pH of a solution is defined as the concentration of hydrogen ion in a solution. It is also the negative logarithmic value of the concentration of hydrogen ion. It determines the acidity or alkalinity of a solution.
HA(aq) + H2O(l) --> A-(aq) + H3O+(aq)
pH = -log[H3O+]
= - log [6.3 x 10-6]
= 5.200
