Ionic Compounds in Solution
Given the following chemical formulas, write a balanced chemical equation that shows how the
ionic compounds will dissociate in water. Be sure to write the correct charges. The first one is
done as an example
1. NaCl
NaCl -> Na+ + Cl2.
2. CaCl2
3. Mg(OH)2
4. HC2H3O2
5. Fe(NO3)3
6. Li2S
7. HNO3
Given the concentrations of each solution, find the concentration of each ion
1. 0.2 M NaCl
Na+ - 0.2M
Cl- - 0.2M
2. 6.2M CaCl2
3. 0.025 M Mg(OH)2
4. 1.6 M HC2H3O2
5. 1.12 M Fe(NO3)3
6. 0.5 M Li2S
7. 2 M HNO3
Give the formula for the 6 strong acids
1. 3.45 g of NaCl was dissolved in 500.0 mL of water.
a. What is the concentration of NaCl?
b. What is the concentration of Na+ ?
c. If 200.0 mL of water was added to the solution, what would the new
concentration be?
2. 100.0 mL of 5.0 M Cu(NO3)2 was poured into a 1 L container.
a. How many mols of Cu(NO3)2 is in the container?
b. 350.0 mL of water was added. What is the concentration of NO3-?
3. 100.0 mL of 3 M HCl was mixed with 100.0 mL of 3 M NaOH.
a. Write the balanced chemical equation and predict the products.
b. What is the concentration of the product formed?
