Predict the formulas for calcium chloride and potassium phosphate

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)

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)

h let me think

answer: option (b) is the correct answer.

explanation:

a covalent bond is formed by sharing of electrons. whereas polarity arises due to difference in electronegativity of two atoms.

therefore, more is the electronegativity of an atom which combines with the titanium, more readily it will induce a partial positive and negative charge.

thus, out of the given options fluorine is most electronegative and has an incomplete octet. therefore, it will readily combine with titanium to share the electrons and complete its octet.
