**1. Given the following reaction: (hint: balance the equation first)**

** H _{2}SO_{4} + 2 NaOH g Na_{2}SO_{4} + 2 H_{2}O**

**If 43.2 mL of 0.236 M NaOH reacts with 36.7 mL of H _{2}SO_{4}, what is the concentration of the H_{2}SO_{4} solution? 0.139 M H_{2}SO_{4}**

**2. Given the following equation:**

** NaOH + HCl g H _{2}O + NaCl**

**If 36.7 mL of HCl solution is needed to react with 43.2 mL of a 0.236 M NaOH, what is the concentration of the HCl solution? 0.278 M HCl**

**3. Given the following equation:**

**Al(OH) _{3} + 3 HCl g AlCl_{3} + 3 H_{2}O**

**How many mL of 1.2 M HCl is needed to dissolve 5.8 g of Al(OH) _{3}? 186 mL of 1.2 M HCl**

**4. Given the following equation:**

H_{2}SO_{4}+ Na_{2}CO_{3}g Na_{2}SO_{4}+ H_{2}O + CO_{2}

**Calculate the molarity of the H _{2}SO_{4} solution if it takes 40.0 mL of H_{2}SO_{4} to neutralize 0.364 g of Na_{2}CO_{3}. 0.0859 M H_{2}SO_{4}**
