What do lemon juice and vinegar have in common? • Chemists consider them as opposites to drain cleaner, baking soda, and ammonia • These subatances can all be classified as acids or bases • Chemistsuseclassification systems to make sense of matter. • Mixtures and pure substances • Elements and compounds • Metals and nonmetals Acids and Bases are types of compounds that have characteristic formulas and similar chemical behaviours, especially when dissolved in water
Acids and Bases • Compounds withparticularproperties • Play differentroles in thefunctioning of your body • Someacids are harmful to your body. e.g • Cells in your body breakdown glucose, CO2 is a byproduct • CO2dissolves in water in yourblood forms H2CO3(aq) • A build up of H2CO3 is harmful • Body converts it to (H+) and (HCO3-) and sent back to thebloodwithout harming the body • Otheracids in your body are DNA- deoxyribonucleicacid • Responsible for passing inheritedcharacteristicssuch as hair colour.
Some bases produced by your body are harmful • Your body producesammonia (NH3) as a wasteproduct of some types of food • Ammonia is toxic to humans, so your body converts it to urea (NH2)2CO). • Urea is not toxic and removed from body in your urine
