Answer 2

Answer:

The Answer should be:-

Citric Acid - Organic Acid

Nitric Acid - Mineral Acid

Basic Salt - Sodium Acetate

Litmus Paper - Indicator

Antacid - Mild Base

Explanation:

• Citric Acid is an organic acid as it is found in nature.
• Nitric Acid is a mineral acid
• Sodium Acetate is basic salt because it is a salt of Acetic Acid & Sodium Hydroxide (NaOH being very strong)
• Litmus Paper is an indicator as it changes colour when added to acid or base.
• Antacids are used during acidity which is caused due to increase of acid content in stomach. So mild bas is used during antacid to neutralize the excessive base.
