what is the purpose of a buffer system
to maintain pH
a good buffer system is a combination of ____ acid and the ____ of its conjugate base
- weak
- salt
what are the properties of acids
- produce hydrogen ions when they dissolve in H2O
- are also electrolytes because they produce H in H2O
- have a sour taste
- turn blue litmus red
- corrode some metals
what are the properties of bases
- produce hydroxide ions (OH) in H2O
- taste bitter/chalky
- are also electrolytes b/c they produce hydroxide ions (OH) in water
- feel soapy and slippery
- turn litmus indicator paper blue and phenolphthalein indicator pink
what does a strong acid do
completely ionize in aqueous solutions
what does a weak acid do
associates only slightly in water to form a few ions in aqueous solutions
what do strong bases do
completely dissociate in water
what does Le Chatelier’s principle state
when equilibrium is disturbed, the rate of the forward and reverse reactions change to relieve that stress to reestablish equilibrium
