Sodium Carbonate was added to solution G with a p. H value of 1.5 ldentify the observation that was made and explain

The evolution of a colourless, odourless gas

Explanation:

If the pH = 1.5, Solution G is acidic.

Sodium carbonate is a base.

It will react with an acid to form carbonic acid, which decomposes into water and carbon dioxide.

2H⁺(aq) + CO₃²⁻(aq) ⟶ H₂CO₃(aq) ⟶ H₂O(l) + CO₂(g)

They observed the evolution of bubbles of a colourless, odourless gas.

- "the choice that is not an indicator of a chemical change is "state of matter changes". more common than not, chemical reactions produce energy in the form of light or heat. along with energy, they also produce a new substance called the product that could be in any state of matter (solid, gas, or liquid)."

i think so it’s will be b yes i believe its
