Answer:
CaCl2
And
potasium phosphate is a general name for salt of potassium and phosphate ions . The compounds can exist as
K3PO4 (Tripotassium phosphate)
K2HPO4 (di potassium phosphate)
KH2PO4 (mono potassium phosphate)
Step-by-step explanation:
Calcium chloride salt is an ionic compound. so it contains both cations and anions. That means it has a positively charged ion and a negatively charged ion. In an ionic compound their is a transfer of electron. The valence electron or the charge ion present in an atom can be use to predict the chemical formula of this compound . Base on the compound the positive end is calcium while the negative end is chlorine .
Ca2+ and Cl-
cross multiply the charges
CaCl2
The charge of phosphate ions are (PO4)3−, (HPO4)2− and (H2PO4)−. And base on the valence electron potassium has a stable charge of +1 (K+). The phosphate ion produces the negative charge when it reacts with potassium.
If potassium goes into reaction with any of the phosphate ion it will be as follows.
K+ and (PO4)3−
cross multiply the charge as usual
K3PO4(tripotassium phosphate)
K+ and (HPO4)2−
cross multiply the charge as usual
K2HPO4(di potassium phosphate)
K+ and (H2PO4)−
cross multiply the charge as usual
KH2PO4 (mono potassium phosphate)
