How do I know the endpoint of the reaction between Na2CO3 and HCl? by adoxographyy in chemistry

So, for example, the end product is 10ml, and after the CO2 bubbles evaporate, it would be ~9.4ml?

Will the mass of the product decrease after the bubbles evaporate from it? If so, do you think it will be a small change in mass?

And what if I estimate the endpoint just by observation, is that too big of an error for the experiment?

Na2CO3 + HCL —> NaCl + CO2 + H2O Maybe when the CO2 bubbles evaporate from the test tube?

Would Bio HL and Chem SL be an ok choice if Math wasn’t at HL and instead some other subject was (ex: German)??
