Swimming pool chemistry is an excellent way for high school chemistry students to study acid-base chemistry this project illustrates that ph is not just a number to be calculated it is a complex concept that is affected by. (a) for the chemical reaction that occurs when the precipitate forms, (i) write a balanced, net-ionic equation for the reaction, and (ii) explain why the reaction is best represented by a net-ionic equation. We can combine our knowledge of acids and bases, equilibrium, and neutralization reactions to understand buffers and titrations solubility equilibria will build on concepts from solubility, precipitation, and equilibrium.

Acids and bases for more than 300 years, substances that behaved like vinegar have been classified as acids, while those that have properties like the ash from a wood fire have been called alkalies or basesthe name acid comes from the latin acidus, which means sour, and refers to the sharp odor and sour taste of many acidsvinegar tastes sour because it is a dilute solution of acetic.
