Answer: The correct answer is Option 1, Option 2 and Option 3.
Explanation:
A base is defined as the substance which releases hydroxide ion when dissolved in water.
For the given options:
- Option 1: [tex]NH_3[/tex]
When ammonia is dissolved in water, it produces ammonium hydroxide which forms a basic solution.
[tex]NH_3+H_2O\rightarrow NH_4OH[/tex]
- Option 2: [tex]Na_2O[/tex]
When sodium oxide is dissolved in water, it produces ammonium hydroxide which forms a basic solution.
[tex]Na_2O+H_2O\rightarrow 2NaOH[/tex]
- Option 3: [tex]LiOH[/tex]
When lithium hydroxide is dissolved in water, it produces aqueous lithium hydroxide which forms a basic solution.
[tex]LiOH+H_2O\rightarrow LiOH(aq.)[/tex]
- Option 4: [tex]P_4O_{10}[/tex]
When phosphorus pentoxide is dissolved in water, it produces phosphoric acid which forms an acidic solution.
[tex]P_4O_{10}+6H_2O\rightarrow 4H_3PO_4[/tex]
Hence, the correct answer is Option 1, Option 2 and Option 3.
