What will be the observation when you will add aqueous sodium hydroxide is added to aqueous iron 3 sulphate?
Green Percipitate
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!!!!!!!!!!!
Why is Sodium Sulphate used in Lead Acid Batteries?
Sodium Sulphate greatly extends the number of useful cycles the battery can go through (charge/discharge), it also extends the amount of time a given current can be taken before the voltage starts to fall significantly. Not all batteries have this added but the more expensive ones with over 500 cycles claimed almost always have it. Batteries offering only 200 cycles or so will hardly ever have the sulphate added - but around 20g per cell for a normal battery CAN be added if the battery is new or in generally good condition. Adding it to older batteries with a lot of "sludge" and/or sulphate crystals can encourage the battery to develop an interal short.
What is added to sodium hydroxide that will get sodium sulphate and water?
You would need to add Sulphuric acid to make Sodium Sulphate + Water :)
What is observed when sodium sulphate solution is added to barium chloride?
White precipitate of barium sulphate
Why does strontium sulfate becomes less soluble in an aqueous solution when sodium sulfate is added?
Sodium sulphate increases the concentration of sulphate ions. So strontium sulphate solubility decreases.
When sulphuric acid is added to sodium bicarbonate why does the colour change?
this makes sodium sulphate and CO2

Barium chloride in excess is added to be sure that the reaction is complete.

What happen when you added Sodiun hypo chloride in Sodium Sulphate solution?
I think sodium Hypo chlore is act as a color removal reagent. it is used to develop the sulphate color to white. If any other reasones are there please inform me.
