Test For Aqueous Cations - Sodium Hydroxide
here might be a way to clasify the cations under the effects of sodium hydroxide according to their differences and similarities to be easier remembered. =)
today, i used blue pen for half of the map reading test absent mindedly.
and i only realised i did when bhavani then sitting beside me exclaimed in panic,
oh my god beat you used blue pen!
now i have to re-copy everything. =(
