It is OK to use your textbook or lecture notes from class, but if you can answers the questions without it that is OK too.

Do not press the RETURN or ENTER key while you are answering these questions. Your browser will interpret either the same as clicking on the Submit key.

Answer all of the questions below. If you do not know an answer enter CNA. However, it will help me the most if you answer each question with your best intuition/idea about what would be a reasonable answer.


First Name:

Last Name:

School:

1. For each of the following compounds indicate the solublity in water. If soluble, identify the ions formed in solution. (NOTE: Do not forget the charge on each ion.) Here is a Solubility Table to help answer this question. When entering ions like Mg2+ enter Mg^2+.

Substance (formula)

Solubility (Soluble/Insoluble)

Cation

Anion

a) K2CO3

b) Al(NO3)3

c) Ca3(PO4)2

d) NH3

2. Predict the product(s) for the following reaction. Balance the equation and use the Solubility Table to identify the phase of each product. For each product assume the first cell is the coefficient, the second the formula and the third the phase. (NOTE: Look at Example 4.3 on page 143 in your textbook.)

a) NaOH(aq) + FeSO4(aq) ----> +

b) H2SO4(aq) + Ba(OH)2(aq) ----> + (NOTE: This is a neutralization reaction. Check out Example 4.6 on page 148 in your textbook.)

 

3. Is there anything about the questions that you feel you do not understand? List your concerns/questions.

4. If there is one question you would like to have answered in lecture, what would that question be?
