Why do you need to add distilled water in a potassium iodate solution in a volumetric flask until it reaches 250ml?

To dilute it to a certain concentration given in moles. It is best to transfer it to a beaker first to make sure it dissolves. The 250ml figure is dependent on how much of the solution that you need

What is a volumetric flask and its uses?
A volumetric flask is a piece of laboratory glassware used in analytical chemistry for the preparation of solutions. It is made of glass or plastic and consists of a flat bottomed bulb with a long neck, usually fitted with a stopper. The stopper is normally made in a chemically resistant plastic such as polypropylene rather than glass. The neck has a single ring graduation mark and a label. The label should show the nominal volume, tolerance, calibration temperature, class, relevant manufacturing standard and the manufacturer’s logo. The glass or plastic is generally clear but may be amber colored for handling light sensitive compounds such as silver nitrate or vitamin A.
What happens when a solution reaches the saturation point?
Saturation is the point a solution reaches where no more solute will dissolve in the solvent.
Why is a white tile used in an acid - base titration?
It makes it easier to see the colour change in the solution after it reaches its endpoint.
How do you prepare 100 mM Na carbonate bicarbonate buffer PH 9?
Insufficient information. The desired molarity or normality of the solution is required. For 100 mL of 1.0 molar sodium carbonate dissolve 10.59 grams of anhydrous sodium carbonate in 100 mL water.

What is a superated solution?
Almost every chemical that dissolves (solute) in a solution eventually reaches a proportion of solute to solvent where no more material will dissolve. The extra just falls to the bottom. This is saturated solution. However if you "play tricks" on the saturated solution. For example cooling it gently so the solution is holding more solute at the lower temperature than it should. The solution is said to be supersaturated. This is usually a unstable condition. A tap on the container or the introduction of a dust mote or particle of the solute, will result in the precipitation of the excess solute from the solution.
What is a flask and its uses?
Volumetric flask, also known as measuring flask or graduated flask, is a kind of glassware which is used for accurate dilutions and preparation of standard solutions. Volumetric flasks are usually pear-shaped with a graduation mark on the neck. The mark indicates the volume when the solution reaches there. Volumetric flasks are various in size, but they come in standard size, 10.00 ml, 25.00 ml, 50.00 ml, 100.0 ml, 250.0 ml, 500.0 ml, etc.

What is the reaction when potassium carbonate is put into water?
A strong electrolyte dissociates completely into ions in aqueous solution. When potassium nitrite, a strong electrolyte, is put into water the cations and anions are surrounded by water molecules and the solid dissolves.KNO2(s) K+(aq) + NO2-(aq)We represent this state by the symbol "(aq)" to indicate that the ions are in aqueous solution.

Saturation is the point a solution reaches where no more solute will dissolve in the solvent.
What will happen if a highly concentrated substance is added to a solution?
It will gradually diffuse until it reaches equilibrium.

It makes it easier to see the colour change in the solution after it reaches its endpoint.
What is the state of potassium at 25 degrees Celsius?
potassium has melted by time it reaches 20 degrees.

How can you tell that a solution of water and kosher salt reaches a saturation point?
When it is impossible to dissolve any salt further at a given temperature.
