A

-ous

63
Q

When it comes to naming acids if the ending of an anion is -ide, what is the prefix and the ending of the corresponding acid

A

prefix is hydro-

ending is -ic

64
Q

When adding acids what would you do to neutralize the charge?

A

add as many H+ ions to make the charge zero (ex. sulfate “SO42-“ equals H2SO4)
