Type of acid for hydrochloric acid, HCl
Is a strong acid
The formation of the hydroxonium ions, H3O+
Is the product of a dative bond formed between hydrogen ion, H+ with water molecule
Weak acid
Is an acid that ionises partially in water to produce low concentration of hydrogen ions, H+
The reason which ethanoic acid, CH3COOH is a weak acid (1)
Because the molecules of ethanoic acid, CH3COOH ionise partially in water
The reason which ethanoic acid, CH3COOH is a weak acid (2)
The degree of dissociation of ethanoic acid molecules is 1.54%
The reason which ethanoic acid, CH3COOH is a weak acid (3)
From 100 molecules of ethanoic acid, CH3COOH, only one molecule of ethanoic acid, CH3COOH ionises to hydrogen ions, H+ and ethanoate ions, CH3COO–
The reason which ethanoic acid, CH3COOH is a weak acid (4)
The rest still exist as molecules of ethanoic acid, CH3COOH
Type of acid for ethanoic acid, CH3COOH
Weak acid
Partial ionisation of ethanoic acid, CH3COOH
