7 acid P : hydrochloric acid/ sulphuric acid/ nitric acid.

 Acid P/ hydrochloric acid/ sulphuric acid/ nitric acid is a strong acid//ionize completely in water

to produce high concentration of H+ ions.

It will cause the pH value to be lower (smaller).

acid Q : ethanoic acid.

 Acid Q/ ethanoic acid is a weak acid // Ionise partially in water

(ii)

 Ionic compound

1. Correct charge of ion

2. correct number of electron in the shell for each ion

3. contain nucleus

Explanation

Ionic compound

  Electron arrangement of an atom of element W is 2.8.1 

  2 Atom W donates one electron each to achieve the stable electronarrangement which is 2.8

  2 W ion, W+ is formed

  Electron arrangement of atom X is 2.6 

  Electrons from atom W are transferred to an atom of X 

  Atom X receives TWO electrons to achieve the stable  electron

arrangement which is 2.8.

  W ion, X2-is formed

  The W ion, W

and X ion X

2-

 , formed are attracted to one anotherto form an ionic compound, W2X

  The strong electrostatic  forces between the opposite-charged ions

is called ionic  bond.

Covalent bond

  Atom V has four  valence electrons, with an electron arrangement

of 2.4

  It needs four  more electrons to achieve the stable  electron

arrangement

  One atom of X contributes 2 electrons for sharing

  Atom Xhas SIX valence electrons, with an electron arrangement of2.6

  It needs two more electron to achieve the stable  electron

arrangement

  One atom of v share a pair of electrons with two atoms of x

  Covalent compound of VX2 is formed
