6. Write and balance the neutralization reaction of HCl and Ba(OH)2 HOH + BaCl2

7. Write and balance the neutralization reaction of sulfuric acid (H2SO4) and aluminum hydroxide (Al(OH)3) 3 2 H2SO4 + Al(OH)3 6 HOH + Al2(SO4)3

8. What is the molarity of a NaOH solution if 75 8. What is the molarity of a NaOH solution if 75.00 mL are required to completely neutralize 50.00 mL of a 1.50 M solution of HBr? MAVA = MBVB 1.50 M x 50.0 ml = MB x 75.0 ml 1.50 M x 50.0 ml = MB 75.0 ml MB = 1.0 M

9. If 60.00 milliliters of a 0.750 M solution of HNO3 are necessary to neutralize 100 mL of a solution of KOH, calculate the molarity of the KOH. MAVA = MBVB 0.750 M x 60.00 ml = MB x 100 ml 0.750 M x 60.00 ml = MB 100 ml MB = 0.45 M

10. If 15.0 ml of a 0.25 M Ca(OH)2 solution are required to neutralize 25 mL of a H2SO4 solution, what is molarity of the H2SO4. MAVA = MBVB MA x 25.0 ml = 0.25 M x 15.0 ml MA = 0.25 M x 15.0 ml 25.0 ml MA = 0.15 M
