We’re being asked to determine the chemical symbol for hydrocyanic acid.
Recall that acids come in two different forms: Binary acids and Oxyacids (or oxoacids).
A binary acid is a covalent compound that contains an H+ ion connected to negative ion.
An oxyacid is a covalent compound that contains an H+ ion connected to a polyatomic ion containing oxygen.
Rules for Naming Binary Acids:
a. The prefix will be hydro-
b. Use the base name of the nonmetal (anion)
Write the formula for each acid.
