LAB LIQUIDS refers to the liquids used in a laboratory setting. These liquids are typically either ACIDS or bases, which are both important components of many experiments. ACIDS are substances that have a pH lower than 7 and can be identified by their sour taste. Bases, on the other hand, have a pH higher than 7 and can be identified by their bitter taste. Common examples of ACIDS include hydrochloric acid (HCl) and sulfuric acid (H2SO4), while common examples of bases include sodium hydroxide (NaOH) and potassium hydroxide (KOH).
