Q. What are the properties of acids?
Solution:
1. Proton Donors: Acids are special substances that like to “give away” tiny particles called protons (H⁺ ions). When an acid mixes with water, it lets go of these protons, which can interact with other things.
2. Taste and Feel: Acids often taste sour. The sourness in lemons comes from something called citric acid, and vinegar gets its tangy taste from acetic acid. If acids touch your skin, they might sting or burn, so be careful!
3. pH Levels: Acids have a pH number that is less than 7. The pH scale is like a ruler that measures how strong or weak an acid is. A smaller number means the acid is very strong!
4. Acid Reaction:
With Bases: Acids can team up with bases to make water and a special substance called salt. This process is called neutralization.
With Metals: Some acids can fizz and bubble when they meet certain metals, making hydrogen gas.
With Carbonates: Acids can also make bubbles of carbon dioxide gas when they meet things like baking soda or chalk.
5. Natural Cleaners: Acids like lemon juice or vinegar can clean rusty objects because they react with the rust.
6. Color Changer: Acids can change the color of special materials called indicators. For example, they turn blue litmus paper red!
7. Electricity Helper: Some acids in water can carry electricity, so they can help power things in the right conditions.
