Copper sulphate add to sodium hydroxide result colour?
Calcium sulphate + Sodium hydroxide > Sodium sulphate + Calcium hydroxide
When you mix a few drops of phenolphthalein solution to a beaker of pure water mixed with calcium hydroxide what happens?
the colour changes to pink
How to tranform cupric sulfate to cupric hydroxide?
Put drops of Sodium, Potassium, or Ammonium Hydroxide in it. The Cupric hydroxide will precipitate out in blue colour. Dont put excess hydroxide or there will be a formation of another intense blue complex compound
What is the color of precipitate of copper II oxide from copper II hydroxide?
Well if u want the colour of precipitate of Copper II Oxide, that would be black, if its Copper I Oxide then its Red
How do you distinguish sodium hydroxide and sodium acetate?
To test presence of Sodium ions, do a flame test: color observed: golden yellow. To test presence of carbonate or hydrogen carbonate ions: Take some of the sodium hydrogen carbonate in a dry test tube. Heat the test tube and bubble the gas through limewater. Limewater turns milky. Carbonate or hydrogen carbonate ions present. To distinguish between carbonate and hydrogen carbonate: Add indicator solution. If colour of solution turns green, pH is 7-8, hydrogen carbonate ions are present. If colour of solution turns blue, pH is 12-13, carbonate ions are present. -Iberuz
Solution contains metallic ion blue in colour flame test produce blue green colour The solution forms a precipitate when sodium hydroxide is added to the solution What is the ion in the solution?
Most likely copper.
Copper sulphate add to sodium hydroxide result colour?
Calcium sulphate + Sodium hydroxide > Sodium sulphate + Calcium hydroxide
When you mix a few drops of phenolphthalein solution to a beaker of pure water mixed with calcium hydroxide what happens?
the colour changes to pink
In a reaction between sodium sulfate and calcium chloride what is the name of the precipitate formed and what colour is it?
the precipitate is calcium sulfate (CaSO4) and its white in color
Why is sodium hydroxide or ammonia a suitable reagent for cation testing?
Sodium hydroxide solution often produces a precipitate when mixed with a solution containing a metal cation. The colour of this solid is indicative of which cation you have, for instance copper hydroxide is light blue and iron(II) hydroxide is green. Ammonium hydroxide can also produce these precipitates, but the reactions are sometimes more complex.
What colour is the precipitate formed when sodium hydroxide reacts with potassium iodide?
They are not soluble, therefore they do not precipitate or form a color....a.k.a....no reaction...
What 2 solutions can be used to test for carbon dioxide?
lime water turns milky in the presence of CO2 Limewater (a solution of Calcium hydroxide) - when carbon dioxide is blown through the solution, a precipitate of Calcium carbonate is produced. The solution is said to turn "milky" or "cloudy". Bromothymol blue (pH range 2.4 to 4.6) (red in colour) is added to distilled water, which turns it yellow. Carbon dioxide turns the resulting yellow solution green.
What is the colour of calcium hydroxide?
White as pure, dry substance
What will be the colour of precipitate of lead nitrate solution?
metalicc or grey
What does quicklime and water make?
A vigorous reaction between water(steam) and quicklime produces calcium hydroxide as a residue.
What happens when ammonia solution is added to copper sulphate?
A precipitate is formed which has a light blue colour. After shaking, the precipitate re-dissolves forming a dark blue solution.
What results from copper II nitrate reacting with sodium hydroxide?
Solutions of copper (II) compounds will undergo precipitation reactions with sodium hydroxide solution when mixed together to produce a bright blue precipitate of copper (II) hydroxide and a solution of a sodium salt.The chemical equations for the reaction between Copper (II) nitrate and Sodium hydroxide are as follows:Cu(NO3)2 (aq) + 2NaOH (aq) → Cu(OH)2 (s) + 2NaNO3 (aq)Copper II nitrate + sodium hydroxide → copper II hydroxide + sodium nitrate
