Can you explain what happens to the particles of potassium chloride when they dissolve in the water?

when particles of KCl are put in water, they dissolve because KCl being a polar ionic compound, its ions separate and in aqueous solutions, water molecules surround these ions with the partially positive hydrogen ions closer to the chloride ions and the partially negative oxide ion towards the potassium ion but the electron cloud is bigger on the side of the chloride ion since it's more electronegative and the attraction between the hydrogen and the chlorine and between oxygen and potassium becomes stronger than that between potassium and chlorine hence the two ions [potassium and chloride] are pulled apart forming ions in the solution

Explain why acetyl chloride is hydrolyzed faster than benzoyl chloride?
bcos there s a strong resonance n benzoyl chloride so that can't easily loose electrons..........
Explain how electrostatic dust preciptators remove smoke particles from chimneys?
remove it.
Compare the boiling and freezing points of 1m solution of glucose to a 1m solution of Cacl2. Why does CaCl2 have a higher boiling and a lower freezing Please explain not just say its 1m and then 3m?
Boiling and freezing points are colligative properties, meaning they depend on the number of solute particles dissolve in solution. Glucose is a molecular compound so it is one particle dissolved in solution. CaCl2 will dissociate into three particles in solution. There are three times as many particles present in solution when CaCl2 dissolves.
Explain how the poisionous elements sodium and chlorine can be eaten when combined?
NaCl(s) or sodium chloride, is commonly known as table salt.
Explain why deaminase activity must be determined immediately following the addition of ferric chloride?
because the color produces fade quickly.
Do all solid particles dissolve in water explain your answer?
Water acts as a solvent. Solvents are "dissolvers". Water acts as a solvent. Solvents are "dissolvers".
Can you describe and explain the precipitates that form when potassium chloride reacts with silver nitrate?
When solutions of potassium chloride and silver nitrate dissolved in water are combined, they react to form the insoluble compound silver chloride and the slightly soluble compound potassium nitrate. Both compounds precipitate as white solids. The reaction looks like this: KCl (aq) + AgNO3 (aq) -> AgCl (s) + KNO3 (s)
How does a particle theory explain how a solute dissolves into a solvent?
You can use the particle theory to help explain what happens when solutes dissolve. The particle theory states that there are spaces between all particles. This means that, in a sample of water, there are many water particles, but also many empty spaces. When you look at sugar. The sugar dissolves, the sugar particles separate and mix with the water particles.
Is it always possible to distinguish two substances from one another based on their appearance explain your answer using specific examples?
Generally is not possible; a chemical/physical analysis is needed.Examples: the appearance of sodium chloride and potassium chloride is similar, the appearance of ethanol and methanol is similar etc.
Why you are using K2Cr2O7 for chloride test explain reaction?
Potassium dichromate react with chlorides (adding sulfuric acid) and form chromyl chloride; this compound is released as specific red fumes. The reaction is: K2Cr2O7 + 4Cl- + 6H2SO4 --- → 2CrO2Cl2 + 2KHSO 4 + 4HSO 4-+3H2O
Explain why water is able to dissolve many ionic compounds?

Will hydrogen chloride gas (HCl) dissolve in water Explain why.?
Hydrogen chloride, or hydrochloric acid (HCl), has two atoms, hydrogen and chlorine. The strengths these atoms have on the nearby electrons are quite different, ie they have different electronegativities. This therefore means that one atom has a stronger pull on the electrons than the other. This is known as a polar molecule. Water (H2O) is also a polar molecule, and when two polar chemicals are mixed, they will dissolve, so the HCl will full delocalise, and become two separate H+ and Cl- ions.

Explain how a solute can dissolve in polar and nonpolar solvents?
=a polar solvent dissolves a polar solute, and nonpolar solvents dissolve nonpolar solutes. likes dissolve likes=
What is ammonium chloride made of?
Ammonium Chloride is most obviously made of Ammonium and Chloride. Now let me REALLY explain it. Since NH4+ has a charge of +1 And Cl has a charge of -1 Ammonium Chloride's chemical notation is NH4Cl.
Explain how solids are terms in particles?
In a solid, the particles are tightly packed and do not move around much, as opposed to a liquid or gas, in which the particles are more spread out.
