Predict if the solutions of the following salts are neutral, acidic or basic: `NaCl, KBr, NaCN, NH_(4)NO_(3), NaNO_(2)` and `KF`

Explanation

To determine whether the solutions of the given salts (NaCl, KBr, NaCN, NH₄NO₃, NaNO₂, and KF) are neutral, acidic, or basic, we need to analyze the components of each salt. Each salt is formed from a specific strong or weak acid and base. Here's a step-by-step breakdown:

### Step 1: Identify the components of each salt

1. **NaCl**: Sodium chloride is formed from sodium hydroxide (NaOH) and hydrochloric acid (HCl).
2. **KBr**: Potassium bromide is formed from potassium hydroxide (KOH) and hydrobromic acid (HBr).
3. **NaCN**: Sodium cyanide is formed from sodium hydroxide (NaOH) and hydrocyanic acid (HCN).
4. **NH₄NO₃**: Ammonium nitrate is formed from ammonium hydroxide (NH₄OH) and nitric acid (HNO₃).
5. **NaNO₂**: Sodium nitrite is formed from sodium hydroxide (NaOH) and nitrous acid (HNO₂).
6. **KF**: Potassium fluoride is formed from potassium hydroxide (KOH) and hydrofluoric acid (HF).

### Step 2: Classify each salt based on the strength of its acid and base

1. **NaCl**:
- Strong acid (HCl) + Strong base (NaOH) → Neutral solution.

2. **KBr**:
- Strong acid (HBr) + Strong base (KOH) → Neutral solution.

3. **NaCN**:
- Weak acid (HCN) + Strong base (NaOH) → Basic solution (strong base dominates).

4. **NH₄NO₃**:
- Strong acid (HNO₃) + Weak base (NH₄OH) → Acidic solution (strong acid dominates).

5. **NaNO₂**:
- Weak acid (HNO₂) + Strong base (NaOH) → Basic solution (strong base dominates).

6. **KF**:
- Weak acid (HF) + Strong base (KOH) → Basic solution (strong base dominates).

### Summary of Predictions
- **NaCl**: Neutral
- **KBr**: Neutral
- **NaCN**: Basic
- **NH₄NO₃**: Acidic
- **NaNO₂**: Basic
- **KF**: Basic
