FORMULA
ACID + METAL -> SALT + HYDROGEN
BASES
ALL ALKALIS ARE BASES
NOT ALL BASES ARE ALKALIS
OXIDES, HYDROXIDES AND CARBONATES
THESE ARE ALL BASES
EXAMPLES
MGO = MAGNESIUM OXIDE
CUCO3 = COPPER CARBONATE
CAOH2 = CALCIUM HYDROXIDE
THE PH SCALE
ACID AND ALKAIIES
ACIDS WERE ON THE LEFT
RED WAS A STRONG ACID
ALKALIES WERE ON THE RIGHT
A STRONG ALKALI WAS A DARK PURPLE
WE CAN USE UNVIVERSAL INDICATER TO TELL WHAT PH IT IS
THIS CAN COME AS TWO DIFFERENT FORMS
PAPER
LIQUID
ALTERNATLY WE CAN USE A PH MONITOR RIGGED UP TO A COMPUTER
ACIDS AND ALKALIES
MIXING TOGETHER CAUSES NUTERLISATION
ACID + ALKALI -> A SALT + WATER
WHEN NUETERLISATION TAKES PLACE YOU END UP WITH SALTY WATER
IF YOU EVAPERATED THE WATER YOU WOULD BE LEFT WITH SAT
IF YOU MIX AN ACID AND ALKALI THEY CANCEL EACH OTHER OUT
IT WOULD BE A NEUTERAL SUBSTANCE WITH A PH OF 7
THE ACID AND ALKALI MUST BE OF THE SAME STRENGTH AND AMOUNT
