WebThe values of Van't Hoff factors for lithium chloride, magnesium oxide, and aluminum phosphate are_ a. 2,2,2 b. 2,2,3 c. 1,1,2 d. 1,1,1 Science Chemistry CHEMISTRY 123 Answer & Explanation Solved by verified expert Answered by Chemistry000123 Physical chemistry Step-by-step explanation ans a LiCl ---> Li^+ Cl^- i= 2 MgO ---> Mg^+2 + O^-2 … WebThe value "i" is called the van't Hoff factor (named after the first person to win the Nobel Prize in Chemistry). It is a little weird at first, so I will show you some examples and then explain in a moment: For sodium chloride, NaCl, i = 2 For magnesium chloride, MgCl2, i = 3 For glucose, C6H12O6, i = 1 For sodium sulfate, Na2SO4, i = 3

Web14 sep. 2024 · b) K₃PO₄ : i=4 since one phosphate anion and three potassium cations are ionized. c) Li₂CO₃ : i=3 since one carbonate anions and two lithium cations are ionized. d) NaNO₃: i=2 since one nitrate anion and one sodium cation are ionized. Therefore, K₃PO₄ has the largest van't Hoff factor as more ions are formed during its dissolution. The van 't Hoff factor is the ratio between the actual concentration of particles produced when the substance is dissolved and the concentration of a substance as calculated from its mass. For most non-electrolytes dissolved in water, the van 't Hoff factor is essentially 1. Meer weergeven The van 't Hoff factor i (named after Dutch chemist Jacobus Henricus van 't Hoff) is a measure of the effect of a solute on colligative properties such as osmotic pressure, relative lowering in vapor pressure Meer weergeven Similarly, if a fraction $${\displaystyle \alpha }$$ of $${\displaystyle n}$$ moles of solute associate to form one mole of an n-mer ( Meer weergeven This quantity can be related to the osmotic coefficient g by the relation: $${\displaystyle i=ng}$$. Meer weergeven • When solute particles associate in solution, i is less than 1. For example, carboxylic acids such as acetic acid (ethanoic acid) or benzoic acid form dimers in benzene, so that the number of solute particles is half the number of acid molecules.
