The metal is copper (Cu)
Its cation is Cu^(2+)
This cation in solution with sulphates or chlorides forms a BLUE aqueous solution.
What else can I help you with?
Red litmus will turn blue when placed in an aqueous solution of?
Blue in Base
What is the action of litmus with aqueous solution Na2CO3?
Red litmus paper turn blue in basic solutions; sodium carbonate solution is basic.
Why is the aqueous solution of Cu2 plus blue?
The aqueous solution of Cu2+ ions appears blue due to the absorption of certain wavelengths of light. The blue color is a result of the d-d electron transitions within the copper ions, where the electrons absorb energy and transition to higher energy levels, leading to the absorption of specific colors in the visible spectrum, giving the solution its characteristic blue color.
What is then colour of litmus paper when metal oxide is dissolved in water?
When a metal oxide is dissolved in water, it typically forms a basic solution. In this case, blue litmus paper will remain blue, indicating the basic nature of the solution. If the metal oxide were to produce an acidic solution, red litmus paper would turn blue, but this is less common for metal oxides.
What colour would litmus paper turn when dipped in an aqueous solution of aspirin?
Litmus paper would turn blue when dipped in an aqueous solution of aspirin, indicating the solution is basic. aspirin is a weak acid and when dissolved in water, it undergoes hydrolysis releasing hydroxide ions which makes the solution basic.
What is cuso4 aqueous colour?
NO such formula as ' cuso4 ' . If you mean ' Copper sulphate' then the formula is ' CuSO4 ' NOTE the use of capital letters. See my note below!!!!! The colour of aqueous CuSO4 is BLUE. NB When writing chemical formula. #1 Single letter elemental symbols are ALWAYS a CAPITAL letter. #2 Double letter elemental symbols are first letter is a capital letter, and the second letter is small/lower case. This is the International recognised symbolism and as shown in the Periodic Table. It is done to avoid confusion!!! ' CO ' is carbon monoxide ' Co' is cobalt. Hence Copper is 'Cu' NOT 'cu' Sulphur is 'S' NOT 's' Oxygen is 'O' NOT 'o'.
Red litmus will turn blue when placed in an aqueous solution of?
Blue in Base
What is the action of an aqueous solution of borax on litmus?
An aqueous solution of borax will have a slightly basic pH. Litmus is a pH indicator that turns blue in basic solutions and red in acidic solutions. Therefore, when litmus is added to an aqueous solution of borax, it will likely turn blue.
Blue food color in Lysol?
It creates a clear aqueous solution with a blue tint.
What is the action of aqueous solution of borax on litmus paper?
Aqueous solution of borax is basic in nature and will turn red litmus paper blue. This is because borax can accept protons from water, making the solution basic.
What is the color of light absorbed by an aqueous solution of copper sulphate?
An aqueous solution of copper sulfate absorbs light in the blue-green region of the spectrum. This is because copper ions in the solution absorb light of longer wavelength, leaving behind the blue-green color.
Does the litmus paper test determine if an aqueous solution is basic?
Yes, the litmus paper test can determine if an aqueous solution is basic. If the litmus paper turns blue, it indicates that the solution is basic. If it remains red, the solution is acidic.
How do you prove metal oxide is basic?
when ash of magnesium is dissolved in water then magnesium hydroxide is formed. MgO + H2O---->Mg{oh}2 hence, the solution is basic in nature.The oxides of metals are basic in nature.Therefore,their aqueous solution turns red litmus blue.
What is the action of litmus with aqueous solution Na2CO3?
Red litmus paper turn blue in basic solutions; sodium carbonate solution is basic.
Why is the aqueous solution of Cu2 plus blue?
The aqueous solution of Cu2+ ions appears blue due to the absorption of certain wavelengths of light. The blue color is a result of the d-d electron transitions within the copper ions, where the electrons absorb energy and transition to higher energy levels, leading to the absorption of specific colors in the visible spectrum, giving the solution its characteristic blue color.
What are the properties of bases when they are in an aqueous solution?
Bases in an aqueous solution typically feel slippery, taste bitter, turn red litmus paper blue, and have a pH greater than 7. They can also conduct electricity when dissolved in water.
What is the action of aquoes solution of borax on litmus paper?
An aqueous solution of borax is basic in nature. When litmus paper is dipped into the solution, it will turn blue or remain blue, indicating that it is a base. Litmus paper changes color in response to the pH level of the solution it is placed in.
