Calculate the pH of the resulting solution obtain

Question

Calculate the pH of the resulting solution obtained by mixing 20 mL of0.2M HCl solution and 50 mL of 0.1M NaOH solution by assuming completedissociation of HCl and NaOH in the solution?

Vikas TU · Accepted Answer

As both are the strong acids and bases respectively, the Resultant moles after totally gets dissociated would be => 50*0.1 – 20*0.2 => 5 – 4 = 1 mmoles of NaOH would get remained.Molarity would be => 1/70Therefore, pOH = -log(1/70) = 1.84pH = 14-1.84 => 12.16
