Sort these salts into the chlorides, the sulphates and the sodium salts. A salt can be in two families.
NaCl, KCl, , , , .
Need a reminder? The key ideaShow
A salt has the positive ion of a base and the negative ion of an acid. Strong acid + strong base gives a neutral salt; strong acid + weak base, an acidic one; weak acid + strong base, a basic one. Electrolysis of brine gives NaOH, and .
The worked solution
Have you tried it?
Work it out on paper first. It is fine to get stuck or make a mistake: that is how we learn. When you are ready, go through the solution one step at a time, and check each step against your own.
Step 1. Chlorides. NaCl, KCl, .
Step 2. Sulphates. , .
Step 3. Sodium salts. NaCl, , .
Answer: NaCl and belong to two families each.
