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.

definition

                    entropy is a measure of the randomness or the extent of disorder of a chemical process.

                      enthalpy is a measure of the heat change of a reaction occurring at a constant pressure.

measurement units:

                        entropy is measured in joule per kelvin (jk⁻¹)   whereas enthalpy is measured in joule per mole (jmol⁻¹)

requirements:

                            entropy has no requirements or limits, and its change is measured by the division between the heat change of the chemical process and the temperature.

                              in contrast, enthalpy can only be related to the heat change of the reaction under standard conditions.
