Firstly, what do you mean by "lower"? Do you mean less exothermic? If that is what you mean, then one possible reason is that your anhydrous copper sulphate was not truly anhydrous, and that is highly likely. Did it look a bit blue? If so then it had absorbed some water from the air and therefore you did not weigh out as many moles of it as you had thought - hence less heat was released in your experiment.

How many grams of anhydrous sodium sulphate should be used to prepare Sodium sulphate solution 60ml where Each ml contains 0.1mmol of Na plus?

To calculate the mass of anhydrous sodium sulfate needed, you first need to determine the total moles of Na+ required. In this case, 60 ml * 0.1 mmol/ml = 6 mmol of Na+. Anhydrous sodium sulfate has a molecular weight of 142.04 g/mol, so you will need 6 mmol * 142.04 g/mol = 852.24 mg or 0.85224 grams of anhydrous sodium sulfate to prepare the 60ml solution.


What substance changes blue anhydrous copper sulphate crystals to white?

Water changes blue anhydrous copper sulphate crystals to white by creating hydrated copper sulphate, which is white in color.


What colour is pure water when anhydrous copper sulphate is added and is there a soild residue?

Anhydrous copper sulfate solid is white. When it is added to water, it dissolves and the solution of aqueous copper sulfate becomes blue.


What are a few examples of anhydrous crystals?

Anhydrous copper sulphate is a paler blue compared to hydrous copper sulphate. See the related link for further information.


What colour is anhydrous copper sulphate once heated?

Anhydrous copper sulfate is white powder, heating makes no difference.


What is the definition of relative formula?

Why does the water colour change to blue when copper sulphate was added?

Anhydrous copper(II) sulphate is white. When added to water, it forms a solution of CuSO4(aq) which is blue because of the Cu2+ ion, which is itself a transition metal ion.


Is anhydrous copper sulphate reversible?

Anhydrous copper sulfate (CuSO4) is reversible in the sense that it can absorb water molecules from the environment to form hydrated copper sulfate. Conversely, hydrated copper sulfate can be heated to drive off the water molecules, regenerating anhydrous copper sulfate. This process is reversible as it involves only physical changes and not chemical reactions.


Chemical formula of sodium sulphate?

Anhydrous sodium sulphate is Na2SO4


When added to copper sulphate what colour is anhydrous copper sulphate?

anhydrous copper sulphate is white. when water is added it turns blue, in essence it can be used to detect the presence of water. hope this helps!!!!!!!!!!!
