Answer:
Resulting solution is Na₂SO₄ of molarity 0.006M.
Explanation:
The balanced chemical reaction is;
→
We know that 1cc = 1ml
Moles of in 100ml of 1M H₂SO₄ solution=
Moles of NaOH in 20ml of 5M NaOH solution=
But we know from balanced equation, 2mol of NaOH reacts with 1mol of H₂SO₄.
∴ for given 0.5 moles of H₂SO₄ remain unreacted.
Final volume of solution
Molarity of resulting solution of
