Baking soda’s formula does not show any relationship water molecules.

Citric acid is not a mineral acid. It is an organic acid or edible acid that is obtain from organic compounds

If 10 ml of H₂SO₄ is mixed with 10 ml of Mg(OH)₂ of the same concentration, the result solution be MgSO₄ which is a neutral salt and universal indicator will give the green colour in this solution

Baking powder is a mixture of sodium hydrogen carbonate and tartaric acid NaHCO₃ + H+ → CO₂ + H₂O + Sodium salt (from tartaric acid) of acid Carbon dioxide (CO₂) produced during reaction can cause bread or cake to rise and makes Baking powder, tartaric acid neutralises the salt and cake does not taste bitter.

Sodium carbonate (Na₂CO₃) is the salt of carbonic acid (H₂CO₂) and sodium hydroxide (NaOH). Here NaOH is a powerful base and carbonic acid is a weak acid.

C₂H₅OH is not a base. C₂H₅OH is an organic compound with –OH functional group that is known as alcohol

Common salt (NaCl) is formed after a reaction between hydrochloric acid (HCl) and sodium hydroxide (NaOH)
