To determine which reaction would yield a neutral salt, we need to analyze the nature of the acids and bases involved in each reaction given in the table.

1. [tex]$2 NaOH + H_2SO_4$[/tex]
- [tex]\(NaOH\)[/tex] is listed under strong bases.
- [tex]\(H_2SO_4\)[/tex] is listed under strong acids.
- A strong acid reacting with a strong base typically results in a neutral salt.
- Reaction: [tex]\(2 NaOH (strong\, base) + H_2SO_4 (strong\, acid)\)[/tex]
Yields a neutral salt ([tex]\(Na_2SO_4\)[/tex]) and water.

2. [tex]$NaOH + HCN$[/tex]
- [tex]\(NaOH\)[/tex] is listed under strong bases.
- [tex]\(HCN\)[/tex] is listed under weak acids.
- A strong base reacting with a weak acid results in a basic salt.
- Therefore, this reaction does not produce a neutral salt.

3. [tex]$KOH + HF$[/tex]
- [tex]\(KOH\)[/tex] is listed under strong bases.
- [tex]\(HF\)[/tex] is listed under weak acids.
- A strong base reacting with a weak acid results in a basic salt.
- Therefore, this reaction does not produce a neutral salt.

4. [tex]$2 NH_4OH + H_2SO_4$[/tex]
- [tex]\(NH_4OH\)[/tex] is listed under weak bases.
- [tex]\(H_2SO_4\)[/tex] is listed under strong acids.
- A weak base reacting with a strong acid results in an acidic salt.
- Therefore, this reaction does not produce a neutral salt.

From the above analysis, we can conclude that the reaction:

[tex]$2 NaOH + H_2SO_4$[/tex]

is the one that yields a neutral salt.
