Explanation:
<h3><u>Answer</u>;</h3>
pH =7.58
<h3><u>Explanation;</u></h3>
The KOH will react with the HClO to produce KClO. You will have a solution containing unreacted HClO and KOH. This is a buffer solution.
Equation:
HClO + KOH → KClO + H2O
HClO reacts with KOH in 1:1 molar ratio
Mol HClO in 50mL of 0.150M solution = 50/1000*0.150 = 0.0075 mol HClO
Mol KOH in 30mL of 0.150M solution = 30/1000*0.150 = 0.0045 mol KOH
These react to produce 0.0045 mol KClO and there is 0.0030 mol HClO unreacted
Volume of solution = 50mL + 30mL = 80mL = 0.080L
Molarity of HClO in solution = 0.0030/0.080 = 0.0375M
Molarity of KClO in solution = 0.0045/0.080 = 0.0562M
Using the Henderson-Hasselbalch equation we can calculate the pH;
pKa HClO = -log ( 4.0*10^-8) = 7.40
pH = pKa + log ([KClO]/[HClO])
pH = 7.40 + log( 0.0562/0.0375)
pH = 7.40 + log 1.50
pH = 7.40+ 0.18
pH = 7.58
