Let’s find out what happens when lemon juice, an acid, is mixed with some white powders found in your kitchen.
1. Line up 3 small bowls or cups.
2. Add about 1 teaspoon table salt into the first one, 1 teaspoon of sugar into the second one, and 1 teaspoon of baking soda
into the last one.
3. Add about 1/4 cup of water to each bowl and stir.
4. Add five drops of lemon juice to each bowl and see what happens. Record your observations in the table below. Which solution
reacted with the lemon juice? How? All acids will react in a similar way–so now you know a test for acids.
5. Carefully wash out the bowls and dry them with paper towels.
