dilute hydrochloric acid
react with sodium hydroxide​

Answer 1

Question: Reaction of Dilute Hydrochloric Acid with;

(i) Magnesium Ribbon

(ii) Sodium Hydroxide.

(iii) Calcium Carbonate

$\rule{421}{1}$

Answer:

(i) Reaction of Dilute Hydrochloric Acid with Magnesium Ribbon:

Dilute Hydrochloric Acid reacts with Magnesium ribbon to form Magnesium Chloride and Hydrogen gas.

Chemical Equation:

$\sf HCl_{(aq)} + Mg_{(s)} \ \longrightarrow \ MgCl_{2 (aq)} + H_{2 (g)}$

Balanced Equation:

$\sf 2HCl_{(aq)} + Mg_{(s)}\ \longrightarrow \ MgCl_{2 (aq)} + H_{2 (g)}$

$\rule{421}{1}$

(ii) Reaction of Dilute Hydrochloric Acid with Sodium Hydroxide.

Dilute Hydrochloric Acid reacts with Sodium Hydroxide to form Sodium Chloride and Hydrogen.

Chemical Equation:

$\sf HCl_{(aq)} + NaOH_{(aq)}\ \longrightarrow \ NaCl_{(aq)} + H_2O_{(l)}$

Balanced Equation:

$\sf HCl_{(aq)} + NaOH_{(aq)} \longrightarrow \ NaCl_{(aq)} + H_2O_{(l)}$

$\rule{421}{1}$

(iii) Reaction of Dilute Hydrochloric Acid with Calcium Carbonate.

Dilute Hydrochloric Acid reacts with Calcium Carbonate to form Calcium Chloride, Carbon dioxide gas, and hydrogen.

Chemical Equation:

$\sf HCl_{(aq)} + CaCO_3_{(s)} \longrightarrow CaCl_{2(aq)} + CO_{2(g)} + H_2O_{(l)}$

Balanced Equation:

$\sf 2HCl_{(aq)} + CaCO_3_{(s)} \longrightarrow CaCl_{2(aq)} + CO_{2(g)} + H_2O_{(l)}$

$\rule{421}{1}$
