Q. What are acids and bases?
Top Answer
Solution:
An acid is a substance that tastes sour (like lemon juice), can turn blue litmus paper red, and reacts with some metals to produce bubbles (hydrogen gas). Acids release hydrogen ions (H⁺) when dissolved in water. Examples include vinegar, lemon juice, and stomach acid.
A base is a substance that tastes bitter, feels slippery (like soap), and can turn red litmus paper blue. Bases release hydroxide ions (OH⁻) when dissolved in water. Examples include baking soda, soap, and toothpaste.
