Basic Nature of Lime water and Baking soda
First, let's understand the concept of basic and acidic substances. Basic substances have a pH level higher than 7, while acidic substances have a pH level lower than 7.
Lime water:
- Lime water is a basic solution that has a pH greater than 7.
- It is made by dissolving calcium hydroxide in water, resulting in a solution with a high pH.
- Lime water is commonly used in laboratories to test for the presence of carbon dioxide, as it turns milky when exposed to carbon dioxide due to the formation of calcium carbonate.
Baking soda:
- Baking soda, also known as sodium bicarbonate, is another basic substance.
- It has a pH level higher than 7, making it a basic compound.
- Baking soda is commonly used in cooking as a leavening agent to help baked goods rise. It reacts with acidic ingredients to produce carbon dioxide gas, which causes the dough to expand and rise.
Conclusion:
- Both lime water and baking soda are basic in nature as they have pH levels higher than 7.
- Therefore, the correct answer to the question is option 'C' - Both (a) and (b) are basic in nature.
