Re: mystery substance
Very strong chemical mixture. It will be an mixture of aluminiumoxide and -flouride.

Re: Finding out pH of the solution
I dont know where you get the ml. Both acetic acid and sodium acetate are added as the mass. To get ml need specific gravity of 100% Acetic acid and sodium acetate is anyway a salt or need concentration before adding.

Re: chemistry reactions
I dont think there is a special reaction. Maybe olny exchange to Gold sulfate and beryllium chloride.

Re: Finding out pH of the solution
The chemical reaction is wrong. Its only a mixture of acetic acid and sodium acetate. There is no reaction. You forget the lightning on the right side. Leftside you have a negative charge what gives thunder storm on the right side. :mrgreen: On the other hand the calculation of pH is correct because...

Which product will be solid?
The ions of that have to been used.

Re: MnCl2 won't dissolve?
How is the demineralzed water made. Maybe organic from manufacturing inside. Use destilled water instead. Add 1 ml HCl to get pH of 5 to 6.
Or the crued product contain oxidiser substances.

Re: chemical reactions
Write down the mass action law for this reaction. K is not given here. This information is missing.
Convert all compounds to SI units. Calculate H2 and N2 to mole via density and molar mass.
Fill in the mass action law equation use x.

Re: pH determination problems
Used wrong formula H2SO3 is a middle strong acid. pKa1 is 1.8 pka2 is 7.
pH =( pk1 + pk2)/2
pH =(1.8 +7)/2 = 4.4
pH =( pk1 + pk2)/2
pH =(1.8 +7)/2 = 4.4

Re: What is the chemical reaction of sulphamic acid solution with trisodium phosphate solution
Probably only a mixture. You get sulphamate anions an hydrogenphosphate anions. Sodium is spectator.

No
A. Alkaline, B. Neutral C. Neutral, D. Alkaline, E. Acidic, F. Acidic
Explain why.: in A compare NaOH and H2S
The same in the other questions

Re: please help me calculate stoichiometry
Yours is correct. Above they used broken numbers and also not very accurate i would say wrong calculation. Example 7.97 H2O never can come from 1.027 C12H22O11.
