During titration, an endpoint was reached after adding 20 mL of sodium hydroxide solution, NaOH (aq), to 20 mL of sulfuric acid, H2SO4. The sodium hydroxide solution had a concentration of 1.50 mol/L.
What was the initial concentration of the sulfuric acid?
a) 2.25 mol/L
b) 1.50 mol/L
c) 3 mol/L
d) 0.75 mol/L

Explanation:
Molarities of acidic and basic solutions are often used to convert back and forth between moles of solutes and volumes of their solutions, but how were the molarities of these solutions determined? This webpage describes a procedure called titration, which can be used to find the molarity of a solution of an acid or a base.
In titration, one solution (solution 1) is added to another solution (solution 2) until a chemical reaction between the components in the solutions has run to completion. Solution 1 is called the titrant, and we say that it is used to titrate solution 2. The completion of the reaction is usually shown by a change of color caused by a substance called an indicator.
