What happens when copper sulfate and steel wool is mix?
IF THE COPPER SULFATE DISSOLVES IN WATER, HAS A BLUE COLOR. WHEN STEEL WOOL IS MIXED WITH COPPER SULFATE,, THE STEEL WOOL DISSAPEARS, A BROWNISH SOLID FORMS, AND THE COLOR OF THE SOLUTION CHANGES FROM BLUE TO GREEN.Copper is produced.
Why does Bismuth chloride in water appear cloudy?
The cloudiness of Bismuth chloride in water is due to the formation of a suspension of solid particles. When Bismuth chloride is added to water, insoluble compounds are formed which do not dissolve completely, leading to the cloudy appearance.
What happens to copper sulphate solution after 2 days at 21c?
After 2 days at 21°C, copper sulfate solution may undergo some changes due to exposure to air and light. The solution may start to oxidize, forming copper oxide or copper hydroxide precipitates. Additionally, some of the copper sulfate may decompose into copper oxide and sulfur trioxide. Overall, the solution may appear cloudy or have a slight color change due to these reactions taking place over time.
Does the iodine solution change color?
Yes, the iodine solution can change color. It typically turns from brown to blue-black when it comes into contact with starch.
Why is silver nitrate solution unstable?
Silver nitrate solution is unstable because silver ions have a high affinity for ligands present in solution, leading to the formation of insoluble silver compounds. The formation of these insoluble compounds can lead to the precipitation of silver salts from solution, making it appear unstable.
What is the color of phenolphthalein in baking powder?
Phenolphthalein is colorless in acidic conditions and turns pink in basic or alkaline solutions. In baking powder, which is alkaline due to its bicarbonate content, phenolphthalein would appear pink.
What is the color of phenolphethaline in washing soda?
Washing soda is sodium carbonate and phenolphthalein will be pink in colour in a solution of washing soda.
Barium chloride is added to potassium chloride What will be colour of the final solution?
The final solution color will depend on the concentration of barium chloride and potassium chloride. However, in general, barium chloride is white and potassium chloride is colorless, so the final solution will likely appear white or colorless.
What happens when naphthalene and phenolphthalein dissolve in ethanol?
When naphthalene and phenolphthalein dissolve in ethanol it creates a crystal-like powder. The powder will also appear to have a yellow tinge and has no smell.
What is the mechanism of methyl orange in sodium carbonate and hydrogen chloride titration?
Methyl orange acts as a pH indicator in the process of sodium carbonate and hydrogen chloride titration. The addition of methyl orange will indicate the ratio of sodium carbonate to hydrogen chloride by the colour which develops.
Why does copper chloride solution appear to fade in color when mixed with aluminum?
When copper chloride solution is mixed with aluminum, a redox reaction occurs where the aluminum reduces the copper ions to form copper metal. This results in a color change from blue-green (copper chloride solution) to colorless (copper metal precipitate), giving the appearance of fading in color due to the formation of a solid copper instead of a colored solution.
Precipitation point of NaCl in H2O?
A supersaturated solution of sodium chloride in water at 20 oC appear after a concentration of 360 g NaCl/L water.
What is the color of aluminium chloride solution?
The color of an aluminum chloride solution can vary depending on its concentration and oxidation state. Generally, a dilute solution of aluminum chloride appears colorless or pale yellow, while more concentrated solutions may appear yellow or brown due to impurities.
What is the colour of phenolphthalein in tap water?
Phenolphthalein is colorless in tap water, as tap water is typically neutral to slightly acidic. It only turns pink in basic solutions with a pH above 8.2.
What is bromo blue in a neutral solution?
In a neutral solution, bromo blue will appear green. This is because bromo blue changes color depending on the pH of the solution. In a neutral pH, it reflects green light.
What happens when you mix copper II chloride in water and then add aluminum folio into the mixture?
When aluminum foil is added to a solution of copper (II) chloride in water, a displacement reaction occurs where the aluminum reacts with the copper (II) ions. This results in the formation of aluminum chloride and copper metal. The copper metal will appear as a solid precipitate in the solution.
What happens when you put silver nitrate into a salt solution?
If the salt solution contains chloride ion (eg. from table salt, NaCl) then silver chloride will precipitate. Both sodium and nitrate ions stay unchanged in solution. Ag+aq + Cl-aq --> AgCls
