Making Salts Experiment

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

Equipment: 

• 50mL and 200mL beakers
• Dilute HCI (hydrochloric acid)
• Dilute NaOH (sodium hydroxide)
• 25mL measuring cylinder
• Glass stirring rod.
• Spotting tile
• Universal indicator solution
• Tripod
• Gauze mat
• Bunsen burner
• Evaporating basin

Method: 

1. Using the measuring cylinder measure 10 ml of HCI and pour it into your 50 ml beaker. Add dilute NaOH a few drops at a time while stirring with the glass road.
2. Every 10-15 drops stop adding the NaOH and use the glass stirring rod to transfer a drop of the solution to a spotting tile. Test its pH using Universal indicator.
3. Keep adding NaOH and testing the solution by repeating step 2. As you get closer to neutral you may need to test the solution after every drop.
4. Pour the neutral solution into an evaporating basin and evaporate the water out of the solution using the equipment set up shown above.  

Observation: During the experiment we made a lot of different colors by trying to make a green. After we put our solution on the heat it turns out like a salt. It took a lot of time for us to get to the point that we already made green. I enjoyed this experiment because I've learned how to maintain the acid and the base to make green.

1. Write a word equation for this reaction.  HCI + NaOH ------> NaCl + H20
2. What is the name of the reaction happening in step 1?  Neutralization
3. What is the name of the process you carried out in step 4? It's called " Evaporation".
