Question 6 of 6
How can you tell if a precipitate has formed in solution?
The color of the liquid will change.
The solution will become cloudy.
Bubbles will form in the solution.
The solution will become transparent.
Homework Answers
Two clear solutions combine to give precipitate by a chemical reaction. Precipitation is nothing but the compound formed that is insoluble in the solution. Thus the formation of precipitate results in cloudy type of solution. This is due to the formation of insoluble compound.
Option b is right answer.

It is important to think through the reactions that are occurring (or not occurring) and determine how you can rule out the presence of a certain metal ion or how you can posi- tively identify its presence. Use the Solubility Table 1 and Appendix 1 of this manual to understand the precipitation réactions that are observed. You need to consider both the anion and the cation that react to form a given precipitate. The color and the general ap- pearance...
