Titrations

A titration works by using a ___________________________ reaction.

Indicators are used in a titration by changing ___________________ at different pH levels.

In a titration, the solution changes color at the

A titration can be used to determine the _______________ of a solution

A 25.00 mL sample of HCl was titrated to the end point with 15.00 mL of 2.00 M NaOH. The following neutralization reaction occured: $HCl\ \ +\ \ NaOH\ \ \rightarrow\ \ NaCl\ \ +\ \ H_2O$  
What is the molarity of the HCl? 

A 10.00 mL sample of H2SO4 was neutralized by 13.5 mL of 1.00 M KOH by the following reaction:  $H_2SO_4\ +\ \ 2KOH\ \ \rightarrow\ \ K_2SO_4\ \ +\ \ 2H_2O$  
What is the molarity of H2SO4?

A 5.00 mL sample of household ammonia was analyzed by titration with hydrochloric acid according to the following reaction:   $HCl\ \ +\ \ NH_3\ \ \rightarrow\ \ NH_4^{\ +}\ \ \ +\ \ Cl^{\ -}$  
This titration required 19.5 mL of 0.750 M HCl. What is the molarity of the ammonia sample?
