Laboratory Lessons


I find laboratory lessons fun and enriching. We were given a chance to conduct experiments on the topics we had learnt. Like this, it would be much easy to understand it as we would be able to see with our own eyes. I definitely enjoyed the laboratory lessons as we would be able to experience it ourselves without just reading it from a book. At first, I was not able to understand the topic on acid and bases, however, after conducting experiments like 2P06 When Acid Meets Alkali, I am able to see more clearly. When an Acid mixes with an Alkali, salt and water would be formed. We conducted an experiment with dilute hydrochloric acid and dilute sodium hydroxide solution and after the mixture was evaporated to dryness, we observed that a white solid was formed and it was salty in taste. Hence we can conclude that an acid reacts with an alkali to produce a salt. Hydrochloric acid + sodium hydroxide -> sodium chloride + water. I hope that there would be more laboratory lessons in the future.
