Words and meanings to learn
neutralisation
a reaction between an acid and a base (like a carbonate) to form water and a salt, usually resulting in a neutral pH
carbon dioxide
a gas produced when an acid reacts with a carbonate, often observed as bubbles or effervescence
salt
a product formed when an acid reacts with a carbonate, containing the metal from the carbonate and the non-metal from the acid
carbonates
compounds that contain the carbonate ion (CO3²⁻)
effervescence
