What is the colour of barium chloride solution?
A solution of barium chloride is added to a solution of potassium chromate, a yellow precipitate forms.
When an acid reacts with a metal the liquid changes colour to green?
This depends on the metal; nickel chloride solution is green.
What is formed when Cobalt chloride is tested with steam?
Cobalt (II) chloride dihydrated (purple colour) and with more water Cobalt (II) chloride hexahydrated (pink colour) .
What is the colour of the solution if zinc is added to copper sulphate solution?
No colour
Which ion is responsible for the colour that is observed in the CuCl2 solution?
CuCl2(s) = Cu^2_(aq) + + 2Cl^-(aq) In solution the chloride anions )Cl^-) are colourless ; see also dissolved common salt (NaCl) So it must be the copper cations (Cu^2+) that gives the colour blue.
What is the colour of copper chloride solution?
blue
What colour is H2O plus ZnCL2 solution?
A solution of zinc chloride is colorless.
Why is the colour of copper chloride solution blue?
a smurf pooped on it
What is the colour of barium chloride solution?
A solution of barium chloride is added to a solution of potassium chromate, a yellow precipitate forms.
What colour changes will appear when phenolphthalein is mixed with sodium chloride solution?
Sodium Chloride is neutral. And Phenolphthalein is colourless when neutral.
Barium chloride is added to potassium chloride What will be colour of the final solution?
BaCl2- and KCl-solutions have no color, and also none when mixed.
What is meant by the word anhydrous when applied to a chemical?
Anhydrous simply means 'without water'. The opposite is a hydrated substance, in which salt crystals contain water as an integral part of the crystal. For example, anhydrous cobalt(II) chloride, CoCl2, is a blue powder. Add water and you form cobalt(II) chloride hexahydrate, CoCl2.6H2O, which is a pink colour. Anhydrous cobalt chloride can be used to test for the presence of water because of this dramatic colour change. In addition, hydrated copper(II) sulfate, CuSO4.5H2O, forms bright blue crystals. Heating them drives off the water of crystallisation and anhydrous CuSO4, a grey/white powder, is formed. Adding water will reform a blue solution of the hydrated salt.
What colour does litmus paper turn in sodium chloride acid?
- sodium chloride is not an acid - in an acid solution the blue litmus paper become red
Will damp cobalt chloride turn back blue once dried?
Solid Cobalt chloride crystals are pink when hydrated with water. If you heat the crystal, the water of crystallisation in the crystals will evaporate, leaving you with solid anhydrous cobalt chloride crystals which are blue in colour.
What will be the colour of bromothymol blue in a solution of sodium chloride in water?
Sodium Chloride solution has a pH of 7 & the Indicator color is green. Bromothymol blue indicator reflects a pH range of 3.5-9.5
How can you distinguish a Cl from I?
Chloride and iodide ions can be distinguished by the colour of their precipitate which are formed by treatig it with silver nitrate solution.
When an acid reacts with a metal the liquid changes colour to green?
This depends on the metal; nickel chloride solution is green.
