Question

Write the basic radicals and acidic radicals of the following and write the chemical formulae of these compounds: (a) Quick lime (b) Baking soda (c) Ammonium dichromate (d) Sodium chlorate (e) Sodium perchlorate (f) Sodium hypochlorite (g) Sodium chlorite (h) Boric acid (i) Phosphoric acid

Answer 1

Answer: first part ( having positive charge= basic radical ) Ca2+ NH4+ Na+ H+

Second = acidic raducal

O2- HCO3- Cr2O72- ClO3-

Explanation:

quick lime CaO

Baking soda NaHCO3

Ammonium dichromate - (NH4)2cr2O7

d) Sodium chlorate- NaClO3

(e) Sodium perchlorate - NaClO4

(f) Sodium hypochlorite- NaClO

(g) Sodium chlorite- NaClO2

(h) Boric acid - H3BO3

(i) Phosphoric acid- H3PO4
