We’re going to do experiments on the water molecule to discover more about water! We’ll need the lime water solution from a previous experiment. Water is a chemical compound and a polar molecule, and it’s a liquid at atmospheric temperature and pressure. The solid state is known as “ice” and the gaseous form is “water vapor”.

Acids split off a positive ion (H+), which turns a blue litmus solution red. Alkaline solutions contain a negative ion (OH-) which turn red litmus solution blue. Citric acid provides the H+ positive ion, and the lime water provides the negative OH- ion, and when we combine the two, they create a neutral water moelcule.
