To determine if acid or carbonate was in excess initially, you can titrate the reaction mixture with an appropriate base of known concentration. The point where the base completely neutralizes the acid will indicate the amount of acid present initially. Any excess base after this point would suggest that the initial excess was in the carbonate.

What does the acid test tell you about a mineral?
The acid test is used to determine if a mineral contains carbonate minerals. When a mineral fizzes or reacts with acid, it indicates the presence of carbonate minerals such as calcite or dolomite. This test helps mineralogists identify and distinguish between different minerals.
What does acid test tell us about a mineral?
The acid test helps determine if a mineral is a carbonate by observing if it produces bubbles when an acid, usually hydrochloric acid, is applied to it. If the mineral fizzes and produces bubbles, it indicates the presence of carbonate minerals such as calcite or dolomite.
How can you tell when as excess of hydrochloric acid has been added to the evaporating dish with the magnesium?
When excess hydrochloric acid has been added to an evaporating dish with magnesium, you will observe bubbling and fizzing as the magnesium reacts with the acid. Once all the magnesium has been consumed in the reaction, no more bubbles will be produced, indicating that excess acid is present.
How do you know that an acid has been neutralized by sodium carbonate?
You can tell that an acid has been neutralized by sodium carbonate when effervescence (bubbling) occurs, indicating the release of carbon dioxide gas. Additionally, the solution's pH will be closer to neutral after the reaction is complete.
When calcium carbonate and hydrochloric acid react bubbles form. How do you know a reaction occurred?
You can tell that a reaction occurred because you observed the formation of bubbles, which indicates the release of a gas (carbon dioxide) as a product of the reaction between calcium carbonate and hydrochloric acid. The appearance of bubbles is a clear sign of a chemical change taking place.

What reaction can be performed to tell the difference between sodium carbonate and sodium sulphate?
Add a few drops of a strong acid such as hydrochloric acid to sample of the substance. If it is sodium carbonate then it will bubble carbon dioxide: Na2CO3 + HCl -> NaCl + CO2 (unbalanced) In the other case, it won't.
How do you know that an acid has been neutralized by sodium carbonate?
You can tell that an acid has been neutralized by sodium carbonate when effervescence (bubbling) occurs, indicating the release of carbon dioxide gas. Additionally, the solution's pH will be closer to neutral after the reaction is complete.
What can liberate carbon dioxide from a carbonate?
By using acids to react with your carbonate carbon dioxide will be liberate, a similar reaction happened to baking soda( NaHCO3) with sulfuric acid (H2SO4). baking soda contains a carbonate ion (CO3). NaHCO3 + H2SO4 ---> CO2 + H2O + NaSO4 formation of bubbles during neutralization will tell you that a gas is ready to escape(CO2 is the gas).
How can you tell if you have added excess acid?
If you have added excess acid, you may notice a sharp, sour taste in your food or drink. Additionally, the texture of your food may change, becoming grainy or mushy. It's best to taste a small sample before adding more acid to avoid over-acidifying your dish.
How can you tell if the reaction of calcium carbonate and hydrochloric acid is finished?
You can tell if the reaction is finished when there are no more bubbles of gas being produced. This indicates that all the calcium carbonate has reacted with the hydrochloric acid. You can also test by adding a few more drops of hydrochloric acid to see if any additional bubbles are produced.
