Today we made experiment for the water in which fizzy tablet dissolves quickly:
a) in clean water
b) in water with vinegar
c) in water with a salt
The fastest dissolved in clean water with time 1 minute and 8 seconds in water with vinegar 1 Minta time 17 seconds in water with a salt of more than 2 minutes.
In water with a salt dissolves  because salt blocks the dissolution of the tablet.
