What is the colour of copper sulphate crystals before and after heating?
Copper Sulphate crystals before heating r blue....but after heating I dunno , may be u should try and ask your Sci.Miss/Sir I'll get back when I get the other answer .
What is the colour change before and after Aqueous ammonia is added to a test tube containing a precipitate of copper II hydroxide and the precipitate dissolves?
Copper (II) hydroxide is a light bluish color. Adding aqueous ammonia produces the tetraamminocopper 2+ ion, [Cu(NH3)4]++, which is a deep blue.
Rock salt crystallizes from the mineral?
People commonly refer to the mineral halite (NaCl = sodium chloride) as rock salt. Rock salt is formed by the continuous evaporation of sea water. In the sequence of minerals precipitating out of the water halite comes after gypsum and anhydrite (calcium sulphate minerals) and before the rarer types of chlorides like potassium chloride.
What happens when copper sulphate react with potassium cyanide?
There's nothing to drive the reaction, since all the possible combinations are soluble. Before, you would have copper, sodium, chloride and sulfate ions in solution; after, you would have the same thing. It's not really a reaction if nothing happens.
What s the formula f the predicted product from heating potassium metal an powdered phosphorus?
K3P, potassium phosphide. This is the one that is most likely to be predicted. It contains the P3- ion. Note that potassium actually has nine binary phosphides , (K3P, K4P3, K5P4, KP, K4P6 K3P7, K3P11, KP10.3, KP15 Before heat the metal and phosphorus (under vacuum and with extreme care) I would weigh out the reactants in exactly the correct proportions to minimise the potassium rich or phosphorus rich compounds.

How do you test for aluminum in potassium alum?
You can get nice crystal if you dissolve Kalunite mineral in clean water and wait till complete evaporation of water. A less expensive way consist to dissolve aluminum sulphate in water and add potash sulphate. The proportion is 70/30 %.
Why do you have to warm the oxalate solution before perfoming the tritration?
I am not sure about this answer.oxalic acid is the strong is acid it need atleast 60 degree or more so that potassium permanganate can give the pink colour.
Does eating potassium cause vomiting?
Consumption of a large dose of potassium ions, such as potassium chloride, induces a vomiting reflex to expel most of the potassium before it can be absorbed
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.
Why is an aqueous solution usually first acidified with dilute nitric acid before adding aqueous lead nitrate?
To keep the kead nitrate in solution: otherwise it might precipitate lead.
What colour was Santas suit before settling to its current red colour?

What is the brightest colour in the world?
Brightest colour is white or just before white
What do dreams have to do with low potassium?
It has been reported that eating foods high in potassium before bed can help you remember your dreams better. Being low in potassium is not related to dreams.
What is potassium manganate coulour before heating?
Dark green
Do you need to fast before a potassium blood test?
yes
