Could someone give me some practice chemistry questions?

E.g. on titration calculations and identifying salts?
E.g. you give me a situation such as, heat a compound X, a lilac flame is produced therefore it is a potassium compound, but I have to give the answer.

Um I don't know if this is what you're looking for, but here you go:

Sulphamic acid reacts with sodium hydroxide according to the following equation:
NH2S03H + NaOH ---> NH2SO3Na + H20
A standard solution of sulphamic acid was made by dissolving 5.210g of the acid in water and making the volume up to exactly 250cm3 with more water

a) Calculate the number of moles of acid used and the molarity of the acid solution.

b) In a titration, 22.6cm3 of this acid solution were required to neutralise 25.0cm3 of sodium hydroxide solution. Calculate the molarity of the sodium hydroxide solution.

What level / Exam board?

a) NH2S03H
5.210 grams
Molar mass = 97

No of moles = 5.210/97 = 0.0537 moles
=> 5.210/97 = (250*C)/1000
=> 5.210/97 = 0.25C
C = (4*5.210)/97 = 0.215 moldm^-3

b)
NH2S03H
V = 22.6cm3 = 0.0226dm^3
C = 0.215 moldm^-3

NaOH
V = 25.0cm3 = 0.025dm3
C = ?

At the equivalence point, the number of moles are equal.

no of moles of sulphamic acid = 0.0226*0.215 = 4.859*10^-3
=> no of moles of NaOH = 4.859*10^-3

4.859*10^-3 = 0.025C
C = 0.194moldm^-3

Can someone check if this is correct? Question is above.

Yes it is correct as far as I can see.

that's good, thankyou.
Do you know anything about the edexcel AS Chemistry practical?

Did you do enthalpy change practice? Something like measure the temperature before and after the reaction ... then draw a graph, from it you can calculate the enthalpy change?

Describe the effect of a nitro-substituent on directing the site of reaction in the electrophilic substitution of an aromatic compound (e.g. benzene). Rationalise that effect by considering charge stabilisation.

read what I am typing, I am not doing that!

widomaker, where did you get your avatar? I think i might steal it I made mine! I can't be bothered searching...

lol, I saw it quite familiar, is it in "spirited away" ?

Please don't steal my avatar.
Can anyone give me any other practice questions?
ask me questions about safety, titrations and precautions to be taken, and identifying salts (edexcel) mainly groups 1,2 and 7.

Sorry about that
I'm sure you'll be fine in your practical exam. If the question is indentifying a compound , you should remember how to realise all the substance, cations, anions, gas, solid ... either by colour or smell, litmus paper, flame test, ect. Did you have the summary note of these?
