calculate the pH of a solution which is 10.0mL of 0.100M NaOH is added to 25.0mL of 0.100M HCl

Expert Solution

HCl NaOH

MA = 0.1M MB = 0.1M

VA = 25ml VB = 10ml

M = MAVA-MBVB/VA+VB

= 0.1*25-0.1*10/25+10 = 1.5/35 = 0.0428M [ MAVA>MBVB]

M = [H^+] = 0.0428M

PH = -log[H^+]

= -log0.0428 = 1.3685>>>>>>answer
