The best and most correct answer among the choices provided by your question is the second choice or letter B "<span>The K + ion and the negative end of the water molecule."

</span>First you may remember a tip: 

<span>Like dissolves like. This means </span>

<span>polar solvents will get polar and ionic substances dissolved and </span>

<span>non-polar solvents will dissolve non-polar substances. </span>

<span>In KI Potassium K is +vely charged and Iodie I is _negatively charged. </span>

<span>In water H-O-H, Hydrogen is +vely charged and Oxygen is -negatively charged. </span>

<span>Polar ends of water attract opposite ions of KI (or any other ionic or polar substance) thus the ionic compound will dissociate and will be dissolved.</span>


I hope my answer has come to your help. Thank you for posting your question here in Brainly. We hope to answer more of your questions and inquiries soon. Have a nice day ahead!

Answer is: D. The I⁻ ion and the positive end of a water molecule.

Dissociation of potassium iodide in water:

KI(aq) → K⁺(aq) + I⁻(aq).

Solvation is the interaction of solvent (water) with molecules or ions (in this example K⁺ and I⁻) in a solute.

Anion I⁻ has negative charge, so positive end (hydrogen atoms) of a water molecul attracts them.

Solvent (usually a liquid, but can also be a solid or a gas) is a substance that dissolves a solute.

43. A stock glucose standard has a concentration of 1,000 mg/dL. A 1/5 dilution of this standard is made. What would be the fina
Nat2105 [25]

The final concentration of the diluted standard is 0.2 mg/dL.

<h3 /><h3>What is concentration of glucose standard after 1/5 solution?</h3>

Using the dilution formula:

  • C1V1 = C2V2

where

  • C1 is initial concentration
  • V1 initial volume
  • C2 is final concentration
  • V2 is final volume.

Assuming a final volume of 100 mL, and since a 1/5 dilution is made:

C1 = 1.00 mg/dL

V1 = 20

C2 = ?

V2 = 100 mL

C2 = C1V1/V2

C2 = 20 × 1/100

C2 = 0.2 mg/dL

Therefore, the final concentration of the diluted standard is 0.2 mg/dL.
