Binary Acids (H plus nonmetal element)
answer
acids that dissociate into hydrogen atoms and anions in water
question
Name binary acids
answer
you merely add "hydro-" (denoting the presence of a hydrogen atom) to the beginning and "-ic acid" to the end of the anion name.
question
Ternary Acids
answer
AKA oxoacids-formed by hydrogen plus another element plus oxygen
question
Ternary Acids
answer
are based on the name of the anion. In this case, the -ate, and -ite suffixes for the anion are replaced with -ic and -ous respectively. The new anion name is then followed by the word "acid."
