Question

Name 5 acids and 5 bases of your choice and locate them on ph scale.

​

Answer 1

Answer:

Acid are Hydrochloric acid , sulphuric acid , Nitric acid, acetic acid and lactic acid .

Base are Sodium hydroxide, potassium hydroxide, barium hydroxide, calcium hydroxide and sodium carbonate .

Answer 2

Answer:

Acids: Sulphuric acid, Hydrochloric acid, Nitric acid, Citric acid, and Lactic acid.  

Bases: Barium hydroxide, Calcium hydroxide, Potassium Carbonate. Sodium borate, and Sodium acetate.

Explanation:

Any hydrogen-containing material capable of transferring a proton (hydrogen ion) to another chemical is classified as an acid. A base is a molecule or ion that can take a hydrogen ion from acid and accept it. The sour taste of acidic chemicals is generally used to identify them.

Acids:

• Sulphuric acid - H₂SO₄ - pH 2.75
• Hydrochloric acid - HCl - pH 3.01
• Nitric acid - HNO₃ - pH - 3.01
• Citric acid - C₆H₈O₇ - pH - 3.24  
• Lactic acid - C₃H₆O₃  - pH - 3.51  

Bases:

• Barium hydroxide - Ba(OH)₂ - pH - 11.27
• Calcium hydroxide - Ca(OH)₂ - pH - 11.27
• Potassium Carbonate - K₂CO₃ - pH - 10.52
• Sodium borate  - Na₂B₄O₇ - pH - 9.21
• Sodium acetate - CH₃COONa - pH - 7.87
