Making Salts | Science

Welcome to another post on my blog. Last week, in Science, I completed an experiment which was about making salts. Using acid and base, we made salt which was a really fun experiment.

Aim: To produce sodium chloride salt by carrying out a neutralisation reaction

Equipment:

1. 50ml and 200ml beakers
2. HCl (Hydrochloric acid)
3. NaOH (Sodium chloride)
4. 25ml measuring cylinder
5. A glass string rod
6. Spotting tile
7. Pipette
8. Universal indicator solution
9. Element (Hot plate)
10. Heatproof mat

Caution: Safety Glasses, Corrosive, Irritant

Method:

1. Using the measuring cylinder, measure 10ml of HCl and pour it into the 50ml beaker.
2. Add a few drops of NaOH at a time while stirring with the glass rod. 
3. Every 10-15 drops, stop adding the NaOH and use the pipette to transfer a drop of the solution to the spotting tile. Test its pH using the Universal indicator.
4. Keep adding NaOH and test the solution by repeating step 3. As you get closer to netural you may need to test the solution after every drop.
5. After reaching neutral (green), then put the beaker on top of an element at a high temperature. 
6. Leave the element on until the liquid has been evaporated and leaves salt. 

Observations:

Write the word equation for this reaction: HCl + NaOH ⇾ NaCl + water

Hydrochloric acid + Sodium hydroxide ⇾ Sodium chloride + water
