Which root word of the binary ionic compound ends with -ide

a. the metal
b. the positive ion
c. the non metal
d. the group 1 element

C. The non metal

Explanation:-

For formation of a neutral ionic compound, the charges on cation and anion must be balanced. The cation is formed by loss of electrons by metals and anions are formed by gain of electrons by non metals.

The nomenclature of ionic compounds is given by:

1. Positive ion or metal is written first.

2. The negative ion or non metal is written next and a suffix is added at the end of the negative ion. The suffix written is '-ide'.

For example: , cesium is metal having an oxidation state of +1 called as cation and bromine is an anion with oxidation state of -1. Thus they combine and their oxidation states are exchanged and written in simplest whole number ratios to give neutral called as cesium bromide.

the ratio of the conjugate base to the acid required to attain the desired ph.
