Name the salt made in each reaction, and write its formula.
- Hydrochloric acid and potassium hydroxide.
- Nitric acid and magnesium hydroxide.
- Nitric acid and calcium hydroxide.
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. (a) Potassium chloride, KCl.
Step 2. (b) Magnesium nitrate, .
Step 3. (c) Calcium nitrate, .
Answer: as above.
