Question

Some salts, although containing two different metallic elements, give a test for only one of them in solution. Such salts are:

a. Double salts
b. Complex salts
c. Coordination compounds
d. Mixed salts

Answer 1

Complex salts are salts that only give a test for one of the metallic elements in solution.

Step-by-step explanation:

In chemistry, salts that only give a test for one of the metallic elements in solution are called complex salts.

Complex salts are composed of ions that come from both weak acids and weak bases. The overall effect on an aqueous solution depends on which ion exerts more influence on the overall acidity.

Some examples of complex salts include sodium acetate (NaCH3COO), which gives a test for sodium, and calcium carbonate (CaCO3), which gives a test for calcium.
