Interpretation Introduction
(b)
Interpretation:
The oxide which is most ionic and most covalent in nature is to be determined.
Concept introduction:
An oxide can be defined as a chemical compound which consists of at least one atom of oxygen and a metal element in its chemical formula.
Interpretation Introduction
(c)
Interpretation:
The oxide which is most acidic and most basic in nature is to be determined.
Concept introduction:
An oxide can be defined as a chemical compound which consists of at least one atom of oxygen and a metal element in its chemical formula. Acidic oxides are those which when made to react with water forms acid and when made toreact with base forms the corresponding salt. Basic oxides are those which when made to react with water forms base and when made to react with acid forms the corresponding salt.
Interpretation Introduction
(d)
Interpretation:
The oxide that can react with both hydroxide and H+ ions is to be determined.
Concept introduction:
A binary hydride is a chemical compound in which a given element is bonded to hydrogen and hydrogen atom acts as a more electronegative atom.

How to measure distance and calculate rate
For the titration of a divalent metal ion (M2+) with EDTA, the stoichiometry of the reaction is typically:
1:1 (one mole of EDTA per mole of metal ion)
2:1 (two moles of EDTA per mole of metal ion)
1:2 (one mole of EDTA per two moles of metal ion)
None of the above
