2. HItung begin mathsize 14px style open square brackets O H close square brackets to the power of minus sign end stylelarutan campuran

begin mathsize 14px style open square brackets O H to the power of minus sign close square brackets space campuran space  equals fraction numerator left parenthesis open square brackets O H to the power of minus sign close square brackets subscript NaOH cross times V subscript NaOH right parenthesis plus left parenthesis open square brackets O H to the power of minus sign close square brackets subscript Ca open parentheses O H close parentheses subscript 2 end subscript cross times V subscript Ca open parentheses O H close parentheses subscript 2 end subscript right parenthesis over denominator V space campuran end fraction end style   
  

begin mathsize 14px style open square brackets O H to the power of minus sign close square brackets space campuran equals fraction numerator left parenthesis 0 comma 1 right parenthesis cross times left parenthesis 50 space ml right parenthesis plus left parenthesis 0 comma 2 right parenthesis cross times left parenthesis 50 ml right parenthesis over denominator 100 space mL end fraction open square brackets O H to the power of minus sign close square brackets space campuran equals fraction numerator 5 space mmol plus 10 space mmol over denominator 100 space mL end fraction open square brackets O H to the power of minus sign close square brackets space campuran equals fraction numerator 15 over denominator 100 space end fraction equals 15 cross times 10 to the power of negative sign 2 end exponent M open square brackets O H to the power of minus sign close square brackets space campuran equals 1 comma 5 cross times 10 to the power of negative sign 1 end exponent M end style   

3. Hitung pOH campuran

begin mathsize 14px style pOH equals minus sign log open square brackets O H to the power of minus sign close square brackets pOH equals minus sign log left square bracket 1 comma 5 cross times 10 to the power of negative sign 1 end exponent right square bracket pOH equals 1 minus sign log space 1 comma 5 end style  

4. Hitung pH campuran

begin mathsize 14px style pH space campuran equals 14 minus sign pOH space campuran pH space campuran equals 14 minus sign left parenthesis 1 minus sign log 1 comma 5 right parenthesis pH space campuran equals 13 plus log 1 comma 5 end style

Jadi, pH campuran adalah 13 + log 1,5
