Describe the characteristic property of assets (exemplified by dilute hydrochloric acid and dilute sulfuric acid) including effects on litmus paper their reactions with metal bases and carbonates
Accepted Answer
Dilute hydrochloric acid (HCl) and dilute sulfuric acid (H₂SO₄) are both strong acids. They share the following characteristic properties:
Litmus paper: They turn blue litmus paper red, indicating their acidic nature.
Reactions with metal bases: They react with metal bases like sodium hydroxide (NaOH) and potassium hydroxide (KOH) to form salts and water, generating heat in an exothermic reaction. For example:
HCl(aq) + NaOH(aq) → NaCl(aq) + H₂O(l)
Reactions with carbonates: They react with carbonates like sodium carbonate (Na₂CO₃) to produce carbon dioxide gas, salt, and water. For example:
H₂SO₄(aq) + Na₂CO₃(aq) → Na₂SO₄(aq) + H₂O(l) + CO₂(g)
While both acids have these properties, they differ in their strength and concentration. Sulfuric acid is a stronger acid than hydrochloric acid, meaning it can donate protons (H⁺) more readily.
