Answer 1

Explanation:

1. Substances which furnish hydronium ion in solution are Acids.
2. Substances which turn blue litmus solution red are acids.
3. Substances which furnish hydroxyl ion in solution are bases.
4. Substances which turn turmeric paper red are bases.
5. Chemical name for salt which we consume everyday is NaCl or Sodium Chloride
6. Base used as foaming agent in fire extinguisher is baking powder.
7. A commonly used antacid is Milk of Magnesia made of Magnesium Hydroxide base.
8. The substances on which litmus solution has no effect are called Neutral Substances.
9. The colour of turmeric solution in soap solution is red in colour.
10. Examples of any two mineral acids are Hydrochloric acid HCl and Sulphuric Acid and organic acids are Tartari and Citric acids.
11. Sodium Chloride is white in colour and Sodium Bicarbonate which is also white in colour.

Acids:-

• Sour to taste
• Electrolytes
• Turn Blue litmus paper red

Bases:-

• Bitter to taste , soapy to touch
• Electrolytes
• Turn red litmus paper blue.

Neutral do not react with litmus paper and have ph equal to 7.

Acids lower than 7.

Base higher than 7.
