Write balanced chemical equations for the complete neutralization reactions that take place when the following acids are titrate

swat32

Answer:

(a) $NaOH_{(aq)} + HCl_{(aq)} --> NaCl_{(aq)} + H_2O_{(l)}$

(b) $NaOH_{(aq)} + CH_3COOH_{(aq)} --> CH_3COONa_{(aq)} + H_2O_{(l)}$

Explanation:

For a reaction involving sodium hydroxide and hydrochloric acid, the balanced equation of reaction is:

$NaOH_{(aq)} + HCl_{(aq)} --> NaCl_{(aq)} + H_2O_{(l)}$

For a reaction involving sodium hydroxide and acetic acid, the balanced equation of reaction is:

$NaOH_{(aq)} + CH_3COOH_{(aq)} --> CH_3COONa_{(aq)} + H_2O_{(l)}$

For a reaction involving sodium hydroxide and phosphoric acid, the balanced equation of reaction is:

$H_3PO_4_{(aq)} + 3NaOH_{(aq)} --> 3H_2O{(l)} + Na_3PO_4_{(aq)}$
