Chemistry
Astudent prepares a standardized solution of sodium hydroxide by the procedure outlined. the student first prepares a saturated solution of sodium hydroxide using freshly distilled or deionized water. she measures about 5 ml of the saturated solution with a graduated cylinder and diluted to 1 l in a plastic bottle with freshly distilled or deionized water to make a solution that is about 0.1 m. to determine the exact concentration, she puts the naoh solution in a buret and titrates a carefully-weighed pre-dried solid acid of known molar mass. she records the volume of naoh needed to neutralize it and repeats the process several times to determine the concentration of the naoh solution. she calculates the concentration and uncertainty in the concentration of the naoh from the titration data. why did the student not just weigh the sodium hydroxide directly to make the standardized solution?

Ответ:
The correct answer is option c, that is, osmotic pressure.
Explanation:
The development of the force, which takes place when two solutions exhibiting distinct solute concentrations are distinguished by a semipermeable membrane is known as osmotic pressure. It is the least pressure that is required to be imparted to a solution to inhibit the inward pure solvent flow through a semipermeable membrane.
The flow of solvent molecules via a semipermeable membrane to a region of high solute concentration from a region of low solute concentration, until attainment of equilibrium, is done is termed as osmosis.
