calcium insoluble in hydroxide!! lead and _______ soluble in hydroxide! then use the potassium iodide to determine? OMG CORRECT ME.
i totally dunno QA dun ask me!!!
i want die liao!!! QA i don't get it
QA is easy. as long as you keep practise it
really!! is easiest out of all topics. dont need explain too much.
they just keep asking . what is this. what is that. give ionic equation w state symbols.
im quite good at it xD hahaa
i can help you
i'm not good. i never memorise anything at all. the notes 11 pages...
barium nitrate -- sulfate! barium weird name. sulfate werid name too LOL
copper (11) - blue. Fe (ll) - green, Fe (lll) - red brown!
nitrate - aluminium foil(reducing agent) - ammonia gas! chloride - white ppt( like salt de colour!) with silver nitrate
iodide is yellow with silver nitrate (remember the experiment like glitter yellow ? )
others is the zinc, lead, aluminium, calcium!!
zinc (z so weird weird) soluble in NH3
then. calcium. relate to ourselves. so imba only soluble metal in NaOH
n lead and aluminium solube in NaOH, insoluble in NH3. use the iodide! lead give yellow
omg!! i mean for iodide is add lead(ii) nitrate!! :S
gases: need remember chlorine and sulfur dioxide.
chlorine - THE ONLY HAVE COLOUR GAS - greenish yellow. SMELLY!!! bleaching agent!! turn litmus paper white.!
sulfur dixoide (acidic) put the potassium dichromate(remember)- the paper from orange to green!! orange is CASS fav
colour.to my fav colour!
