2. 'Suppose you have a 0.10 M solution of AlBr​ 3​ . What is the concentration of each ion
3. Suppose you want to prepare a 2.50 M solution of sodium chloride. If you only have 0.325
moles of sodium chloride, and you must use it all, how many mL must you prepare?
4. Water can dissolve many compounds What happens when an ionic substance dissolves in it?
5. We discussed how some solutions are electrolytes in this lesson. Which of these would be a
strong one?
6. Suppose you have a sample of HC​ 2​ H​ 3​ O​ 2​ with a concentration of 2.0 M. So, what would be the
[H​ +​ ]?
7. We discussed many properties and characteristics of acids in this lesson. Which of the
following is NOT one that was mentioned?
8. In this lesson we learned about K​ w​ , which is known as the the ion product constant for water.
What is this value?
9. Bases have many useful properties that can be exploited for our own benefit. They are
commonly used to make many things that we use. For example, which of these is associated
with making fertilizer?
10. If a solution is acidic, which of the following is true?
11. PART 1: How many milliliters of concentrated HCl (12.1 M) are needed to make the following
amounts of acid? You must show all work in detail to receive credit. (a) 5.00 L of 0.100 M, (b)
1.00 L of 6.00 M, (c) 2.00 L of 3.00 M, (d) 100 mL of 0.100 M. PART 2: Explain, in detail, how
