can you give examples of acids and alkalis plz?

Thank you for using the Jiskha Homework Help Forum. Here is a site that will explain the difference to you:

Certainly! Acids and alkalis are two categories of chemicals that have different properties. Acids have a sour taste, react with metals to produce hydrogen gas, and turn blue litmus paper red. On the other hand, alkalis have a bitter taste, feel slippery, and turn red litmus paper blue.

Here are some examples of common acids:

1. Hydrochloric Acid (HCl): Found in our stomachs, and also used in chemistry labs.
2. Sulfuric Acid (H2SO4): Widely used in industries such as battery manufacturing.
3. Citric Acid (C6H8O7): Present in citrus fruits like lemons and oranges.
4. Acetic Acid (CH3COOH): Also known as vinegar, it is used in cooking and food preservation.

And here are some examples of common alkalis:

1. Sodium Hydroxide (NaOH): A strong alkali commonly known as caustic soda.
2. Potassium Hydroxide (KOH): Found in soaps and drain cleaners.
3. Ammonia (NH3): Used in cleaning products and fertilizers.
4. Sodium Bicarbonate (NaHCO3): Also known as baking soda, it is used in cooking and as an antacid.

To identify whether a substance is an acid or an alkali, you can use indicators like litmus paper or conduct simple chemical tests.
