I got this question but there are no answers with it I was wondering if you could help?
Na2CO3 is ised to precipitate Pb2+ ions from the tailings of a lead mine.
Pb2+(aq) + CO3/2-(aq) = PbCO3(s)
20 000L of talings has a [Pb2+] of 1.7x 10-3mol/L
When 50kg of Na2CO3 is added the [Pb2+]...
Ionisation and Dissociation
How do you distinguish between ionisation and dissociation processes? For example:
Write equations for each and say which are ionisation and which are dissociation processes.
a) Dissolving ethanoic acid in water
b) Sulfur trioxide gas bubbled into water
c)...
Thanks
Thanks for your help. A question about the magensium and colume of gas question. Since Mg has a valency of +2 and Cl a valency of -1 wouldn't the formula for magnesium chloride be MgCl2 instead of MgCl?
Also another question I have found. Lead chloride establishes an equilibrium, as...
Can some one help me with the following questions:
1.Hydrogen Cyanide forms the weak acid, hydrocyanic acid in water. Give the formula of the conjugate base of hydrocyanic acid
2. In a classroom experiment 8g of pure magnesium is dropped into an excess amount of hydrochloric acid...
