(b) ![NaOH_{(aq)} + CH_3COOH_{(aq)} --> CH_3COONa_{(aq)} + H_2O_{(l)}](https://tex.z-dn.net/?f=NaOH_%7B%28aq%29%7D%20%2B%20CH_3COOH_%7B%28aq%29%7D%20--%3E%20CH_3COONa_%7B%28aq%29%7D%20%2B%20H_2O_%7B%28l%29%7D)
(c) ![H_3PO_4_{(aq)} + 3NaOH_{(aq)} --> 3H_2O{(l)} + Na_3PO_4_{(aq)}](https://tex.z-dn.net/?f=H_3PO_4_%7B%28aq%29%7D%20%2B%203NaOH_%7B%28aq%29%7D%20--%3E%203H_2O%7B%28l%29%7D%20%2B%20Na_3PO_4_%7B%28aq%29%7D)
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)}](https://tex.z-dn.net/?f=NaOH_%7B%28aq%29%7D%20%2B%20HCl_%7B%28aq%29%7D%20--%3E%20NaCl_%7B%28aq%29%7D%20%2B%20H_2O_%7B%28l%29%7D)
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)}](https://tex.z-dn.net/?f=NaOH_%7B%28aq%29%7D%20%2B%20CH_3COOH_%7B%28aq%29%7D%20--%3E%20CH_3COONa_%7B%28aq%29%7D%20%2B%20H_2O_%7B%28l%29%7D)
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)}](https://tex.z-dn.net/?f=H_3PO_4_%7B%28aq%29%7D%20%2B%203NaOH_%7B%28aq%29%7D%20--%3E%203H_2O%7B%28l%29%7D%20%2B%20Na_3PO_4_%7B%28aq%29%7D)
