What kind of reaction is KL AQ AgNO3 AQ AgI s kno3 AQ?

What kind of reaction is KL AQ AgNO3 AQ AgI s kno3 AQ?

Answer Expert Verified. Explanation: The reaction is a double displacement reaction in which a precipitate, AgI is produced.

When dilute solution of AgNO3 excess is added to KI solution positively charged sol of AgI is formed due to adsorption of?

Complete step by step solution: Thus, when dilute aqueous solution of AgNO3 (excess) is added the AgI molecules will adsorb the Ag+ ions. When dilute aqueous solution of AgNO3 (excess) is added to KI solution, positively charged sol of AgI is formed due to the adsorption of Ag+ ions on the surface of AgI molecules.

What happens when potassium iodine solution is added to silver nitrate solution?

Answer. When Silver nitrate ) is added to the potassium iodide (KI), we get a negative charged solution because iodide gets adsorbed from the potassium iodide solution and two new products are formed. Where is a colourless solid and KI is a yellow they are combined to produce the white solid.

When agno3 solution is added into KI solution obtained colloidal sol is 2 points?

When silver nitrate solution is added to KI solution, the precipitated AgI adsorbs iodide ions from the dispersion medium and negatively charged colloidal solution results. Since KI is in excess, iodide ions (I-) will be adsorbed on the surface of AgI particles thereby giving them a negative charge..

Why are negatively charged sol is obtained on adding AgNO3 solution to KI solution?

1M KI, (50×0.1) = 5 milli moles of AgNO3are formed. Hence, there is an excess of KI formed. This leads to the formation of negatively charged colloidal sol and hence it does satisfy the requirements of the question. In case of Option C, 50 mL of 0.

Which of the following is negatively charged solution?

Gold sol and starch sol are examples which are negatively charged.

What is the main reason for stability of colloidal solution?

Solution : The stability of the colloidal sols is due to the presence of charge on colloidal particles. The similarly charged particles mutually rapel. Apart from these sol particles gat solvated and participate in Brownian motion.

What is difference between Sol and gel?

Sol: The liquid state of a colloidal solution is called the sol. Gel: The solid or semi-solid (Jelly like) stage of a colloidal solution is called the gel. The present post discusses about the Difference between Sol and Gel. Definition: The liquid state of a colloidal solution is called sol.

Why colloidal particles never settle down?

Answer: The colloidal particles are smaller and not heavy. They always remain in a state of zig-zag motion, called Brownian movement, which counters the force of gravity acting on colloidal particles and hence, helps in providing stability to colloidal sols by not allowing them to settle down.

Do colloidal particles settle down?

A colloid is a heterogeneous mixture in which the dispersed particles are intermediate in size between those of a solution and a suspension. Because the dispersed particles of a colloid are not as large as those of a suspension, they do not settle out upon standing..
