solution?
(If you're unsure of where to start, make up hypothetical numbers that fit this
situation, and see what happens to the concentration!)
one quarter of the concentration of the standard solution
The concentration must be determined experimentally.
four times the concentration of the standard solution
double the concentration of the standard solution
half of the concentration of the standard solution
Question 7 (1
In testing for the presence of lead (II) ions in solution, Jamaal adds a solution of
sodium nitrate. What will be the conclusion of the test if no precipitate forms?
Lead(II) ions are not present in solution.
Lead(II) ions are present in the solution.
Lead(II) ions are present, but in a very small concentration.
More sodium nitrate solution needs to be added before a conclusion can be
made.
No conclusion can be made in this test.
