Yes, but if you add too much powder the solution will turn out "supersaturated" and you will be able to see the powder sitting at the bottom.
To prepare a chitosan solution, dissolve chitosan powder in an acidic solution (such as acetic acid or hydrochloric acid) with stirring. Adjust the pH as needed and filter the solution to remove any undissolved particles. The concentration of the chitosan solution can be adjusted by varying the amount of chitosan powder used.
Phenolphthalein powder can be dissolved in a solvent like ethanol or propylene glycol. Simply add the powder to the solvent and stir until it dissolves completely. Adjust the solvent amount as needed to fully dissolve the powder.
Juice powder is considered a suspension mixture because it consists of solid particles that are dispersed in a liquid medium but do not dissolve completely. When juice powder is mixed with water, the particles remain suspended rather than forming a homogeneous solution, leading to a cloudy appearance. This characteristic allows the solid components, like flavor and nutrients, to be evenly distributed throughout the liquid, but they can settle over time if not stirred.
buy turmeric powder then take a glass of distilled water add 1 teaspoon turmeric powder to it you will notice that the color of the water turns yellow this solution is your indicator
usually it is stirred. It is stirred because if it is not, the paint might still have powder and ruin whatever you are painting if the powder is put on.
To make a solution of indigo carmine from powder, first measure out the desired amount of indigo carmine powder. Dissolve the powder in a small amount of warm distilled water to enhance solubility, stirring thoroughly. Once fully dissolved, dilute the solution with additional distilled water to reach the desired final volume. Ensure the solution is mixed well before use.
Mg + 2HCl -> MgCl2 + H2 The large amount of foam is due mostly due to hydrogen gas.
Yes, but if you add too much powder the solution will turn out "supersaturated" and you will be able to see the powder sitting at the bottom.
A solution is produced by dissolving a solid in a liquid and when completely dissolved there are no particles to be seen; just a transparent liquid (not if you put milk in your tea). A suspension is created when the tiny particles of a substance which is not dissolvable are stirred into a liquid. You can still tell that the particles are still there, and the liquid is not transparent. Think about the particles of cocoa powder stirred into hot water (without milk). You can find some of the powder left when you have drunk up.
To make phenolphthalein indicator solution from powder, dissolve a small amount of phenolphthalein powder (about 0.1g) in 100mL of ethanol or 95% ethanol and 5% water solution. Stir the mixture until the powder is completely dissolved. This will give you a pink indicator solution suitable for titrations.
To prepare an ascorbic acid solution, dissolve the appropriate amount of ascorbic acid powder in distilled water. Stir the solution until the powder is completely dissolved. Ensure the solution is properly mixed and then store it in a clean container.
To prepare a chitosan solution, dissolve chitosan powder in an acidic solution (such as acetic acid or hydrochloric acid) with stirring. Adjust the pH as needed and filter the solution to remove any undissolved particles. The concentration of the chitosan solution can be adjusted by varying the amount of chitosan powder used.

A powder, like coco, that is absorbed into milk and stirred to make coffe on the go
Phenolphthalein powder can be dissolved in a solvent like ethanol or propylene glycol. Simply add the powder to the solvent and stir until it dissolves completely. Adjust the solvent amount as needed to fully dissolve the powder.
The powder is dry, the solution is wet
