name each ternary ionic compound: KNO3, CACO3, Mg(MnO4)2, CuSO3, Ni(CIO?
please i need help with those chemistry ternary ionic I'm doing poorly in the class I need help, i'd like to have explanation on how you do them my test is tomorrow

You need to memorize the formulas and charges on about 25 common polyatomic ions, which should be listed in your textbook or assigned by your instructor. Memorize the "ate" polyatomic ions first.
KNO3 - potassium nitrate
CaCO3 - calcium carbonate
Mg(MnO4)2 - magnesium permanganate
CuSO3 - copper (II) sulfite
Ni(ClO)2 - nickel (II) hypochlorite
Roman numerals are used on transition metals that can have more than one possible charge. For example, Cu1+ is the copper (I) ion; Cu2+ is the copper (II) ion. Some transition elements have only one possible charge and Roman numerals are not used on them. These include Ag1+, Zn2+, and Cd2+; do not use Roman numerals on these.
But, in addition to the transition elements, some representative elements have more than one possible charge, so Roman numerals are used on them. Sn and Pb are two examples. Sn2+ is the tin (II) ion; Sn4+ is the tin (IV) ion. Pb2+ is the lead (II) ion; Pb4+ is the lead (IV) ion.
As for polyatomic anions, there is a pattern in the naming. You should memorize the formula for "ate" ions first. ClO31- is chlorate. The related ion with one less oxygen ends in "ite."
ClO21- is chlorite. If the ion has two less oxygens than the "ate" form, then it has the prefix "hypo" and the suffix "ite". If the ion has one more oxygen than the "ate" ion, then it has the prefix "per" and the suffix "ate.
ClO41- is perchlorate
ClO31- is chlorate (memorize first)
ClO21- is chlorite
ClO1- is hypochlorite
Notice that the charge is 1- on all these ions.
If CaSO4 is calcium sulfate, then CaSO3 is calcium sulfite. One less oxygen than the "ate" ion ends in "ite".
CO32- is carbonate. Putting a H+ ion with CO32- gives HCO31-. The name is now called hydrogen carbonate or more simply, bicarbonate. The prefix "bi" means hydrogen. Notice that the charge on bicarbonate is 1- compared to carbonate at 2-.
