WHOO WNGLsiH OVaR!! YWEAH ME Good it!!!! Me Winner! `100% WHOO!~

oh ok that helps alot. i almost forgot totally about mono-, di-, and triprotic acids....hehe but how do you know whether an acid is triprotic or mono?

never knew that, so its just a fact that citric ionises more than acetic?

this question was in the '04 neap paper: Citric acid and acetic acid are both weak acids. State why citric acid is stronger than acetic acid. is it something to do with the bonds?.....coz it cant be coz of dissociation....help plz

i dont get (b), so u sub in 3M in the equation and do u just solve to find m? can someone please show me working? i always get stcuk with these questions :( oops dw i just found out how to do it!!! :D ty guys....im just slow

according to conq. chem ..."the enthalpy change, for neutralisation reactions is approx. -56kJ/mol" is that hot? ....lol :D all i noe is that -ve enthalpy is exothermic and +ve is endothermic.:p but i guess it depends on what kind of acid and what base reacts.

oh ok lol ty

I used to know the answer to this question but now i forgot :( "why is sodium hydroxide not used as a primary standard?" i know it might be a stupid question but it has come up and im curious about the answer....:p

u can neutralise with a base but use a weak base so the heat released is kept at a minimum, also use a solid so the acid can be "soaked up" and not spread out causing more damage. Then afterwards, splash lots of water over it and u can clean it up. sodium carbonate can also be used for...

is adding chromium to steel, the same process as galvanising right?

lol ok ......thnx again :D

ok thank you so much for confirming that with me......so if a question asks which one is better, you would say the one which is less reactive out of the two??

if there were two metals (both more reactive than iron) used to protect iron by coating it a layer of the metal. Which one would be better? Would it be the most reactive one out of the two?..........Or would it be the one less reactive out of the two since it wouldnt corrode as much and...
