Did you know?
Potassium fluoride is the chemical compound with the formula KF. After hydrogen fluoride, KF is the primary source of the fluoride ion for applications in manufacturing and in chemistry. It is an alkali halide and occurs naturally as the rare mineral carobbiite. Solutions of KF will etch glass due to the formation of soluble fluorosilicates, although HF is more effective.

WebWrite the proper ionic formula for each of the two given ions. Ca 2+ and Cl − Al 3+ and F − Al 3+ and O 2− Solution We need two Cl − ions to balance the charge on one Ca 2+ ion, so the proper ionic formula is CaCl 2. We need three F − ions to balance the charge on the Al 3+ ion, so the proper ionic formula is AlF 3.
