Question

50ml of 0.2M hcl is added to 3oml of 0.1M koh find the poh of solution

Answer 1

Answer:

Poh of solution is 12.94

Explanation:

as we already know acid and base react with each other to form salts.but according to concentrations of each acid or base the PH of final solution get deviated from PH=7

here in picture posted I explained this with the help of formula of molarity. we know well molarity represents concentration

therefore molarity =H+/OH- concentration in solution.

I explained this in the form of picture posted.

hope you understand this
