Test: Acids Bases & Salts

Litmus paper is used as an indicator to check acids and bases. Acids turn blue litmus red.

Sulphuric acid is a strong acid because it is a mineral acid and dissociates completely into ions. It gives more H+ ions than the rest of the acids.

Hydrogen gas is formed as the metal reacts with the acid to form a salt. Many, but not all, metals react with acids.

Lactic Acid is present in sour milk or curd. The increased acidity causes the milk proteins (casein) to tangle into strong masses or curds.

Turmeric is a natural acid-base indicator. It turns yellow in an acidic medium and changes its colour to red in a basic medium.

The most abundant acid in tomatoes is citric acid, slightly less acidic than vinegar. Your body depends on citric acid to produce energy. Citric acid can help to prevent future stones from forming.
There are ten different acids in tomatoes, but the largest part is citric acid and malic acid. As the tomato ripens with malic acid decreasing and citric acid increasing. energy.

In case of indigestion, we use antacids. Antacids containing bases reacts with acids present in stomach to neutralise it.

All acids contain hydrogen in common. When acids is mixed in water hydrogen ion is produced.

A neutralization reaction is a chemical reaction in which an acid and base quantitatively react together to form salt and water as products.
Acid + Base → Salt + Water

Carbonic acid is a weak acid.

• Strong acids make acidic salts with weak bases and neutral salts with strong bases.
• Weak acids make basic salts with strong bases and neutral with weak bases.
