Which of the following pair of solution having different physical state of solvent ?
Sodium amalgam (a homogeneous alloy of sodium and mercury) and the solution of urea in water are examples of homogeneous mixtures with different physical states of the solvent (solid and liquid, respectively).
Which of the following compound possesses maximum solubility in water ?
Among the given options, pentane-1,2,3,4-tetraol (also known as pentaerythritol) has the maximum number of hydroxyl (-OH) groups, making it the most soluble in water due to its ability to form hydrogen bonds with water molecules.
Which of the following given compound is least soluble in water ?
Hexan-1-ol has the longest hydrocarbon chain and the least number of hydroxyl (-OH) groups among the given options, making it the least soluble in water due to its low polarity and inability to form strong hydrogen bonds.
To convert molarity into which of the following unit of concentration, does not require density of the solution ?
Normality does not require the density of the solution to be converted from molarity. It depends only on the equivalent weight of the solute and its molar concentration.
To convert molality into which of the following unit of concentration require density of the solution ?
To convert molality into percentage by volume (% v/v), the density of the solution is required. This is because molality is a unit of concentration based on the mass of solute per unit mass of solvent, while % v/v is based on the volume of solute per unit volume of solution.
Which of the following unit of concentration does not depend on temperature ?
Which of the following unit of concentration depends on temperature ?
Normality is a unit of concentration that depends on temperature because it is defined as the number of gram-equivalent weights of solute per liter of solution. The gram-equivalent weight varies with temperature, making normality temperature-dependent.
What quantity of potash-alum is required to prepare 500ml solution having strength 1.5 F
What would be the volume of acetone required to prepare 10% v/v acetone solution in 5 lt. Solution ?
For a 10% v/v acetone solution in 5 liters, the required volume of acetone is 10% of 5 liters, which is 0.5 liters or 500 mL.
15 % w/v solution of sugar is prepared by dissolving 1200 gm sugar in water, then, what would be the volume of the solution ?
