acids and alkalis Flashcards
was are acids known as
proton doners
what are bases and alkalis known as
proton acceptors
what colour does litmas paper change
red if acidic
blue if alkaline
what colour does phenolphthalein change
colourless if acidic
bright pink in alkaline
what colour does methyl orange go
red if acidic
yellow if alkaline
what does an acid plus a base create
salt + water
what salts does hydrochloric acid create
chloride salts
2HCl + CuO
CuCl2 + H2O
HCl + NaOH
NaCl + H20
HNO3 + KOH
KNO3 + H2O
HNO3 + NH3
NH4NO3
2HCl + Na2CO3
2NaCL + H2O + C02
what are titrations
this is to find out exactly how mach acid is need to neutralise and quantity of alkali (or vise versa)
acid + metal Carbonate
Salt + Water + Carbon Dioxide
how do you test for titrations
use a glass pipet to get the correct amount of acid into the conical flask
add phenophalin
then use the burette to add in alkali slowly and swirl it until the liquid goes clear
