Title	: ACID-CARBONATE REACTION

Aim	: To observe the reaction between an acid and a carbonate .	

Apparatus : 
Test tubes , sodium carbonate , sulphuric acid , calcium hydroxide 
solution , delivery tube and bung ,

Directions :
Into a test tube add 5 ml of aqueous sodium carbonate or one heaped 
spatula of the anhydrous salt . In another tube add the calcium hydroxide 
to a depth of 1 cm . Place the end of the delivery tube in the hydroxide 
solution . Add 5 ml of the acid to the carbonate and bung the tube immediately .
Observe the reactions in both test tubes until no more changes occur . 

Questions  :
How do you account for the changes occurring in both test tubes ?
Use relevant equations including state symbols to show all the reactions occurring.
