Question

Which is an example of a base?a(lemon juice b(baking soda c(an insolator d( water

Answer 1

Answer:

b) Baking soda

Explanation:

Baking soda is sodium hydrogen carbonate, NaHCO₃.

It reacts with water according to the equation

NaHCO₃ + H₂O ⇌ H₂CO₃ + NaOH

Thus, baking soda is a base because it increases the concentration of hydroxide ions in water.

Water is neutral.

Lemon juice is an acid because it contains citric acid.

An insulator is a substance that does not conduct electricity. Insulators are neither acidic nor basic.
