IGCSE Chemistry ATP Analysis (Latest 2023 / 2024)

Chemistry ATP analysis How to check if a liquid is water? Check boiling point = 100 or melting point = 0 Why it is important to immediately put a bung in the conical flask in an experiment where gas is produced? minimize gas loss/ escape before bung is replaced State the advantage of measuring the volume of gas collected every 10 seconds rather than every 20 seconds more points / data so better / smoother graph / curve / line Why condensers are used? To cool the vapour. So that the gas condense into a liquid Which flask is used in distillation? Distillation/ round bottom flask How to keep the temperature of a apparatus constant? Use water bath How to prevent escape of gas when magnesium is added to sulfuric acid? partitioned container, suspend magnesium on thread, If colour of litmus paper is red what is the pH?
