Question

Can you please check to see if my answer is correct this section is difficult for me and if I get this one correct in Aleks I am able to move forward but I have to get this one correct its on predicting the qualitative acid base properties of salts question is attached 

**Consider the following data on some weak acids and weak bases:** **Acids:** | Name | Formula | \( K_a \) | |-----------------|-----------|-------------------| | Acetic acid | \( \text{HCH}_3\text{CO}_2 \) | \( 1.8 \times 10^{-5} \) | | Hydrofluoric acid | \( \text{HF} \) | \( 6.8 \times 10^{-4} \) | **Bases:** | Name | Formula | \( K_b \) | |-------------|--------------|-------------------| | Methylamine | \( \text{CH}_3\text{NH}_2 \) | \( 4.4 \times 10^{-4} \) | | Ethylamine | \( \text{C}_2\text{H}_5\text{NH}_2 \) | \( 6.4 \times 10^{-4} \) | **Task:** Use this data to rank the following solutions in order of increasing pH. In other words, select a '1' next to the solution that will have the lowest pH, a '2' next to the solution that will have the next lowest pH, and so on. **Solutions to Rank:** | Solution | pH Rank | |-------------------|-------------------------------| | 0.1 M \( \text{CH}_3\text{NH}_3\text{Cl} \) | 1 (lowest) | | 0.1 M \( \text{NaCl} \) | 2 | | 0.1 M \( \text{KF} \) | 3 | | 0.1 M \( \text{NaCH}_3\text{CO}_2 \) | 4 (highest) |
