Why the blue color does not appear in starch solution titration?
Blue color does not appear in starch solution titration because the blue color change is specific to the iodine-starch complex. In the presence of iodine, starch forms a dark blue complex, masking the original color of the solution. This is why the absence of blue color indicates the endpoint of the titration.
Why is the colour of copper chloride solution blue?
The blue color of copper chloride solution is due to the presence of copper ions in the solution. When copper chloride dissolves in water, it forms copper ions (Cu2+), which absorb certain wavelengths of light and reflect blue light, giving the solution its characteristic color.
What is the color of copper nitrate?
Copper nitrate is typically a blue-green color in its solid form. When dissolved in water, it forms a blue solution.
What substance is present if iodine soluntion turns blue-black?
If iodine solution turns blue-black, it indicates the presence of starch. Iodine forms a complex with starch, resulting in the blue-black color.
Why was the mixture stop turning the drops of iodine solution blue after 240 s?
The reaction between iodine and starch forms a blue-black complex. Once all the starch present in the solution has reacted with the iodine, no more blue color will be observed. This explains why the mixture stopped turning the drops of iodine solution blue after 240 seconds.
When mixed with water why does copper sulphate turn water blue?
because when in a solution it forms blue crystals creating a blue colour
Why the blue color does not appear in starch solution titration?
Blue color does not appear in starch solution titration because the blue color change is specific to the iodine-starch complex. In the presence of iodine, starch forms a dark blue complex, masking the original color of the solution. This is why the absence of blue color indicates the endpoint of the titration.
When copper turnings are added to silver nitrate solution why does the solution becomes blue in colour?
The blue color in the solution is due to the formation of copper(II) nitrate, as the copper turnings react with the silver nitrate solution. This reaction forms copper(II) ions which give the solution a blue color, indicating the presence of these ions in the solution.
Why is the colour of copper chloride solution blue?
The blue color of copper chloride solution is due to the presence of copper ions in the solution. When copper chloride dissolves in water, it forms copper ions (Cu2+), which absorb certain wavelengths of light and reflect blue light, giving the solution its characteristic color.
What is the color of copper nitrate?
Copper nitrate is typically a blue-green color in its solid form. When dissolved in water, it forms a blue solution.
What is the acid that reacts with copper 2 carbonate to give a blue solution?
The acid that reacts with copper(II) carbonate to give a blue solution is hydrochloric acid (HCl). This reaction forms a solution of copper(II) chloride, which appears blue due to the presence of copper ions.
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?
The metallic ion in the solution is likely copper(II) ion (Cu^2+). This is based on its blue color in a flame test, which gives a blue-green flame, and the formation of a blue precipitate when sodium hydroxide is added, indicating the presence of Cu(OH)2.
What substance is present if iodine soluntion turns blue-black?
If iodine solution turns blue-black, it indicates the presence of starch. Iodine forms a complex with starch, resulting in the blue-black color.
What happens when copper is added to nitric acid and turns blue?
Copper reacts with nitric acid to produce copper (II) nitrate. In water, it forms a clear blue solution.
Why was the mixture stop turning the drops of iodine solution blue after 240 s?
The reaction between iodine and starch forms a blue-black complex. Once all the starch present in the solution has reacted with the iodine, no more blue color will be observed. This explains why the mixture stopped turning the drops of iodine solution blue after 240 seconds.
When the a solution of acid reacts with a solution of base what forms?
It forms a neutral solution. This process is known as a neutralization reaction
What is the organic compound that reacts when iodine is added to starch solution?
The organic compound that reacts with iodine in a starch solution is amylose, which is a polysaccharide and a component of starch. When iodine is added to a starch solution, it forms a blue-black complex with the amylose present in the solution.
