Question

If we have solution of 4g CH3COONa and 4g NaOH obtained NaCl with efficiency 90% we have to calculate pH oh Nacl and we know that Ka= 1.8x10ˆ-5.

Pleas help me i have exam tnext weak Im strudent but I don't undestant this???

Answer 1

You didn't post all of the problem or you are confusing two different problems. CH3COONa and NaOH will not produce NaCl.
The pH of a solution of NaCl is 7.0
