Question

Complete the table below identifying each unknown as an acid or base. 

 

Unknown Solution

Acid/Base

Concentration (M)

0.01M NaOH

 

 

0.01M HCl

 

 

0.02M NaOH

 

 

0.02M HCl

 

 

0.04M NaOH

 

 

0.04M HCl

 

 

0.08M NaOH

 

 

0.08M HCl

 

 

 

 

  • If you mixed 30mL of 0.9M HCl with 45mL of DI water, what would the concentration be for the resulting solution? 

 

 

  • What are the concentrations (in M) of Na+ ions and OH- ions within 1.30 liters of a 0.7M NaOH solution? 

 

 

  • Given a 0.5M solution of HCl, calculate the [H3O+] and pH. 

 

 

  • A solution has a pOH of 11. What is the [H+]? 
  • Suppose you add 20 drops of 0.2M NaOH to 17 drops of 0.2M HCl. Phenolphthalein has been added to
    the HCl. What color do you suspect the resulting solution will be? Why? 
  •  Assuming sulfuric acid completely dissociates in water, what are the concentrations of H+ and SO-42- in
    350mL of 0.25M H--2SO-4?
