re: HSC Chemistry Marathon Archive I'm a little unsure with the bolded part and Sy do you make these questions up? I could use a few for practice lol.

Yup :)

Re: Buffer solution question Yeah I'm a little unsure if Na has an actual role in the buffer system, or if the CHCOO- ion is just considered and the Na+ from CHCOONa is ignored.

Ace dat shiet bro :)

Buffer solution question Just need some confirmation here since there are no answers. Q. Would 1 L of aqueous solution containing each of the following pairs of substances be a buffer solution or not? Explain why (or why not). Use an equation where appropriate. d. 0.25 mol methanoic...

Yeah I checked MyUni and it doesn't allow you to change units until the 11th of Feb :p

That's what my school did too. Core 1 is terrible LOL

Fair enough. Best of luck :)

What course are you doing btw Safraaz? If you don't mind :)

Re: Acid-base Titration claification Alright, thank you :) And yeah brah dw

It depends on the question - sometimes it's easier to use C1V1 = C2V2 rather than c = n/V. It just makes life easier imo but do whatever suits you.

I tested with C=n/v and it also works. I just got a different answer since wannabesurgeon plugged in the wrong values ie. C1 = 0.3250 not 0.3750

Acid-base Titration claification Alright in Conquering Chemistry it reads: Fill a burette (Figure 8.5 on p. 215 CCPC) with a solution of known concentration (for example sulfuric acid) and adjust the solution level in the burette to the zero mark†; the solution in the burette is called the...

Welcome to the clique. I'll see you around ;)

Thanks OzKo! :)

Do not drop to standard at all costs. It is extremely difficult to gain a band 6 as I think in 2011 only 32 people out of 64,000 attained a band 6. Check the Board of studies website yourself - I'm not making this up. You sound like a moderately strong student, keep advanced english. You can...

Challenge accepted and will be successfully accomplished :)

Re: Determining acidity/alkalinity of a salt Kekeke Thanks Dylan :) Means a lot coming from you

Re: Determining acidity/alkalinity of a salt Alright, thanks a lot guys :) And madharris, can I just ask why the equilibrium will shift left if KOH is a strong base? Is it because that it has a great tendency to attract a proton, hence it does this and forms the reactants, causing the equib to...

Determining acidity/alkalinity of a salt Hey guys. I'm a little stuck on these 2 questions. Q. For each of the salts below, give the formula and state whether you would expect 0.1 mol/L aqueous solutions to have a pH of about 7, less than 7 or greater than 7. Explain why, giving equations...
