Question

Indicate the expected van't Hoff factor for the following compounds

- Rubidium carbonate

- Barium sulfite

- Magnesium dihydrogen phosphate

Hope you can help, thank you!

Answer 1

3 [i=2 Barium Sulfite → Ba So Baso Bazt + 50 - Total ion=2 Magnesium dihydrogen phosphate + Mg(H, pou), Mg(H₂PO4)2 in Mg 2+ + 2 H₂ Pou i = 3]

Rubidium Carbonate → Rb, C03 1. Rb₂ CO₂ 2R6+ + CO2 Total ions = 3. i= 3. 2
Van't Hoff factor measure of the effect of a solute upon colligative properties.

For ionic compounds , van't Hoff factor is equal to the number of ions produced by that compound upon dissociation.

For non-ionic compounds van't Hoff factor is equal to 1.

Van't Hoff factor is denoted by the symbol i.

Rules for naming lonic compounds :- 1. The name of cation is written first followed by the name of anion. 2. For d block elements the oxidation state of the metal is written in Roman numerals enclosed in brackets. 3. The name of a compound always ends in 'ide'.
