Device enabling aqueous solution to be sprayed by direct compression of the sprayed fluid. It includes a motor-driven pump 8 and a double-body tank 5, 10 which are fixed to an axle fitted with two wheels 19. The fluid, introduced into the lateral hopper 1, is stored in the first tank...
An aqueous solution is the combination of one or more items in which water is the solvent that the solute dissolves in. Most often, when you think of water, you think of it as a liquid. However, water is only a liquid at room temperature, as a liquid is the state of an item. Ice...
When Cl(2) water is added to an aqueous solution of potassium halide in presence of chloroform, a violet colour is obtained upon shaking. This confirms the pr

An aqueous solution of a soluble compound (a nonelectrolyte) is prepared by dissolving 33.2 g of the compound in enough water to form 250 mL of solution. The solution has an osmotic pressure of 1.2 atm at 25.0 °C What is the molar mass (g/mL) of the compound?A 6.8 × 102B 28C ...
PROBLEM TO BE SOLVED: To achieve a higher heat exchange performance by increasing area contributing to heat exchange while preventing excessive retention of a refrigerant liquid and an absorbing liquid with a large surface tension on the external surface of the tube. SOLUTION: A plurality of protrud...
What is the pH of an aqueous solution with a hydrogen ion concentration of[H+]=9.8×10−4M? pH-Value: The pH-value of a solution is indicative of the concentration ofH+ions in the solution. It simply tells how acidic or basic a solution is. The pH-valu...
Solutions have four colligative properties: namely boiling point elevation, freezing point depression, vapor pressure lowering, and osmotic pressure, all of which depends on the concentration of the solution. Aqueous solutions are observed to have a higher b...
