Question

Solve the following. SHOW YOUR SOLUTION and BOX YOUR FINAL ANSWER.

1. Calculate the H+ ion concentration of a solution with a pOH value of 4.84. Determine whether the solution is acidic, basic, or neutral.

Answer 1

Given,

pOH = 4.84

We know, pKw= pH+ pOH

Or, pH = pkw–pOH

pKw = 14 at 25°C

So, pH = 14–4.85

= 9.15

As we know pH<7 is Acidic and pH>7 is basic and pH=7 is neutral solution.

So, as pH =9.15 so, the solution is basic.
