Question

Find the value of 0.15M of NaOH

Answer 1

Answer:

since NaOH is a strong electrolyte ,it will dissociate completely as follows -

NaOH == Na+ + OH-

conc. 0.5M 0.5M 0.5M

OH- conc. of NaOH is 0.5 , from this you can calculate pOH. Now you apply pOH+pH =14 (At 25 degree centigrade) to calculate pH of 0.5 M NaOH.

So, pOH=-log[OH-] =- log(0.5) =0.3010 Hence, pH=14 - pH =13.69 .
