Is CaCl2 an acid or base or neutral?
Is CaCl2 an acid or base or neutral?
CaCl2 is a salt of strong acid HCl and strong base Ca(OH)2. Thus it forms a neutral solution when dissolved in water.
Is CaBr2 soluble in water?

What is KF Chem?
Kf is a constant for a given solvent. Kf is called the molal freezing point depression constant and represents how many degrees the freezing point of the solvent will change when 1.00 mole of a nonvolatile nonionizing (nondissociating) solute dissolves in one kilogram of solvent.
Which will have the largest delta TB?
Which will have largest ΔTb? Solution : 65g urea has largest no. of moles(1.0833).
Which is not a Colligative property?
Optical activity depends on the solvent and does not depend on the solute so it is not a colligative property. Depression in freezing point is the lowering of the freezing point of a solvent when a non-volatile solute is added to it.
What is I in the osmotic pressure equation?
i is the van’t Hoff factor. C is the molar concentration of the solute in the solution. R is the universal gas constant. T is the temperature.
