The indicator in a titration changed color after 0.01 mol of sodium hydroxide were added to a sulfuric acid solution for the acid-base reaction shown below:
H2SO4 + 2NaOH → Na2SO4 + 2H2O
How many moles of sulfuric acid are in solution? HINT: The ratio of moles of the sulfuric acid to the sodium hydroxide in this reaction is 1:2.

Answer 1

0.005 moles of sulfuric acid are in the solution

Step-by-step explanation:

• The acid-base reaction you have shown occurs in a 1:2 mole ratio, meaning that for every mole of sulfuric acid, 2 moles of sodium hydroxide are required to neutralize it.
• Since you added 0.01 moles of sodium hydroxide, this would be enough to neutralize 0.01/2=0.005 moles of sulfuric acid.
• Therefore, there are 0.005 moles of sulfuric acid in the solution.
