A pure and fresh solution of silver nitrate is clear.
If iodine solution is added to a leaf, it will turn blue-black in color. This is due to the presence of starch in the leaf which reacts with iodine to produce this color change.
When an acidic substance is added to marigold flower indicator, the color generally turns red or pink. This color change indicates the presence of acidity in the substance being tested.
If Ag+ is added to a dilute solution containing FeCl4-, a white precipitate of AgCl would form. This is because Ag+ ions react with Cl- ions to form AgCl, causing the color of the solution to change from the original color of the FeCl4- solution to white due to the formation of the precipitate.
If phenol red is added to sodium bicarbonate, the color of the solution will change based on the pH. In an acidic solution, phenol red will appear yellow, in a neutral solution it will be red, and in an alkaline solution (such as when sodium bicarbonate is added), it will turn a pink or magenta color.
The reaction between AgNO3 and Na2CO3 forms a white precipitate of silver carbonate (Ag2CO3).
When you mix FeCl3 and KSCN, a blood red color forms due to the formation of Fe(SCN)2 complex. When AgNO3 is added to this solution, a white precipitate of AgSCN is formed, indicating the presence of thiocyanate ions in the solution.
When salt is added to water to change its color, the salt dissolves in the water and does not directly affect the color of the water.
If iodine solution is added to a leaf, it will turn blue-black in color. This is due to the presence of starch in the leaf which reacts with iodine to produce this color change.
I didn't observe anything, because I wasn't there at the time. You presumably were. Write down what you saw. (I'm guessing one thing you might have seen would have been a color change in the solution. The appearance of the copper may also have changed. Describe both those things.)

It does not. -.-

Yes, color change is a chemical reaction. An example of a precipitation is when mixing Silver Sulfur(AgNO3) with Sodium Chloride(NaNO3). So.. AgNO3+NaCl--->AvCl+NaNO3
When ammonia is added to mustard, a color change would typically result in a yellow or orange-yellow color becoming more intense or bright. This is due to the alkaline nature of ammonia enhancing the yellow pigment present in mustard.
you would expect a color change in oil of wintergreen because it has an OH group added to the FeCl3 which causes a purple color
