Why do solutions turn blue?

When you shake the solution in a half-filled bottle, oxygen goes into the solution, oxidizing the methylene blue and turning the solution blue. When the shaking stops, the oxygen comes out of the solution, and it goes back to colorless. This is a reversible redox reaction.

What happens when Cu metal is added to silver nitrate?

Copper is more reactive than silver. Hence when copper wire is dipped in silver nitrate solution it displaces silver from silver nitrate (AgNO3 ) solution forming copper nitrate which is bluish green in color. This is a displacement reaction.

What type of reaction is agno3 k2so4?

double displacement reaction
This is a double displacement reaction.

Is CU 2agno3 an oxidation reduction reaction?

Cu + 2AgNO3→ Cu(NO3)2 + 2Ag. The reaction is a redox reaction.

What is the Colour of AgCl?

Discussion

Precipitate Color Moles/L
AgOH brown 8.2 x 10-5
AgCl white 1.3 x 10-5
AgBr yellow 8.8 x 10-7
AgI yellow 1.2 x 10-8

Which is more reactive, Agno 3 or Cu?

The reaction is a redox reaction. Both oxidation and reduction are taking place simultaneously. Copper is oxidised and silver is reduced. Since copper displaces silver from silver nitrate solution, so copper is more reactive than silver. Cu is a reducing agent, AgNO 3 is an oxidizing agent.

What does Agno 3 do to silver nitrate?

Cu is a reducing agent, AgNO 3 is an oxidizing agent. When copper turnings are added to the silver nitrate solution, a blue-coloured solution is formed after some time. More articles to explore
