Would you expect sodium sulphate or copper sulphate to be colourless?

Copper is a transition metal- these often give rise to colored salts. Sodium is an s block metal these are generally colorless. The reason is that transition metals ions have electrons in an outer d orbitals that can be excited to higher energy levels by visible light.

What happen if you add the copper sulphate to sodium hydroxide?
you get a blue lumpy liquid. copper sulphate + sodium hydroxide -> copper hydroxide + sodium sulphate.
Copper sulphate add to sodium hydroxide result colour?
Calcium sulphate + Sodium hydroxide > Sodium sulphate + Calcium hydroxide
How do you distinguish between copper sulphate solution sodium chloride solution sodium nitrate solution or sodium sulphate solution?
copper sulphate solution-blue sodium chloride (salt) solution-clear sodium nitrate solution- white to clear sodium sulphate solution- white copper sulphate solution-blue sodium chloride (salt) solution-clear sodium nitrate solution- white to clear sodium sulphate solution- white
Is copper sulphate a reactant or a product in the following equation copper sulphate plus sodium hydroxide equals copper hydroxide plus sodium sulphate?
Copper sulfate is a reactant in the equation as stated, because it is present before the reaction has occurred and no longer present afterward.
What is the precipitate of copper sulphate and sodium carbonate?
The copper(III) carbonate is a precipitate.
What happen if you add the copper sulphate to sodium hydroxide?
you get a blue lumpy liquid. copper sulphate + sodium hydroxide -> copper hydroxide + sodium sulphate.
Copper sulphate plus sodium hydroxide?
a big lump of mess i dont think so copper sulphate +sodium hydroxide = Na2So4 +Cu(OH)2 WHICH IS SODIUM SULPHATE AND COPPER HYDROXIDE
Copper sulphate add to sodium hydroxide result colour?
Calcium sulphate + Sodium hydroxide > Sodium sulphate + Calcium hydroxide

What substance is used as a control in a Biuret test?
Biuret reagent is made up of sodium hydroxide and copper sulphate.
Would copper sulphate and sodium react?
I DONT KNOW
What is the composition of fehling's solution?
Fehling's solution A= concentrated aqueous solution of Copper (II) sulphate, Fehling's solution B= solution of Sodium-potassium tarterate + sodium hydroxide.
What is formed when sodium chloride reacts with copper sulphate?
I'm not sure, but I think it wont react because sodium chloride is more stable than any compound may be formed such as sodium sulphate or copper chloride
Where does the sodium sulphate go when copper sulphate mixes with sodium hydroxide?
Nowhere. I assume you are talking about mixing solutions. The sodium ions and sulpahate ions remain in solution.
Is it impossible for an element to replace atoms of anothe element in a compound?
No. In a displacement reaction, that is exactly what happens. If an element low down in the reactivity series is in a compound, and you add an element that is higher placed in the reactivity series. The more reactive element will displace the less reactive element in the compound.Example:Copper Sulphate - Copper is low in the reactivity series and is in a compoundSodium + Copper Sulphate - Sodium is higher in the reactivity series than copper, and is in it's pure elemental form.Copper + Sodium Sulphate - The Sodium that is higher in the reactivity series has switched places with the Copper, which is lower in the reactivity series.FULL EQUATION:Sodium + Copper Sulphate --> Copper + Sodium Sulphate
