Acids, Bases, and Neutralisation

Question 1

Salt

Answer 1

A chemical compound formed through a reaction between an acid or a base where a hydrogen has been replaced by metal ion or an aluminium ion

Question 2

Strength (of an acid)

Answer 2

The degree to which an acid disscoiates

Question 3

Strong acid

Answer 3

An acid that completely dissociates in an aqueous solution (foreward reaction favoured)`

Question 4

Weak acid

Answer 4

An acid that partially dissociates in aqueous solution (partially dissociates in aqueous solution)

Question 5

Oxidation States

Answer 5

A measure of the number of electrons an atom uses to bond with atoms of another element

Question 6

Halogens oxidation numbers rule

Answer 6

F will ALWAYS have -1 oxidation number while other halogens are USUALLY -1 when bonded to low electronegativity elements

Question 7

Disproportionation

Answer 7

Some atoms of an element are oxidised and other atoms of the same element are reduced in the same reaction
