Acid or Base??

15ml unsweetened grape juice
1 Teaspoon baking soda
3 glasses


Line up the three glasses in a line.

Pour water into the 1st glass, baking soda into the second glass and vinegar into the third glass.

Now, add some unsweetened grape juice to all the glasses.

Observe: Water gets the colour of the grape juice, which means water is neutral. When grape juice is added to baking soda the colour changes into green indicating it is a base. When the juice is added to vinegar the colour changes to red indicating it is an acid
