What volume of 180m sulfuric acid must be used to prepare

Question

1. Identify conjugate acid-base pairs in each of the following equations:

a) HC₂H₃O₂ + H₂SO₄ == H₂C₂H₃O₂⁺  +  HSO₄^-

b) CH₃O- + H₃O⁺-> CH₃OH + H₂O

c) HCO₃^- + OH ^- === CO₃^2- + H₂O

2. Calculate [H⁺ ] of  the following:(2)

a) a solution with a pH  = 2.4.

b) [OH^-] =  1.8 x 10^-11

^3. Calculate the pH following:

a) vinegar, 2.8 x10^-3 M [H⁺]

b) black coffee, 5.0 x10^-5 M [H⁺]

4. What volume in mL of0.245M HCl will neutralize 50.0 mL of 0.100M Ca(OH)2?

The equation is as follows:

2HCl (aq) + Ca(OH)₂  (aq)  -> CaCl₂ (aq) + 2H₂O (l)

5. If 29.26 mL of 0.430M HCl neutralize 20.40 mL of Ba()OH)₂ solution, what is the molarity of Ba(OH)₂ solution? The equation is as follows: (2)

Ba(OH)₂ (aq)  + 2HCl (aq) -> BaCl₂ (aq) + 2H₂O (l)

6. What volume of 18.0M sulfuric acid must be used to prepare 50.0 L of 5.00M solution?
