What is a saturated solution that cannot dissolve any more solute because it is too concentrated?

1 answer:

4 0

Answer: A saturated solution, by definition, contains an amount of solute equal to the amount of dissolved solute in equilibrium with an undissolved solute. We could, however, make a supersaturated solution in which the solvent contains more solute than would be in equilibrium with undissolved.

Explanation: More solute cannot be dissolved at a given temperature in a saturated solution. This is because the solute dissolves in a solvent due to the space between the solvent particles, but with the continuous addition of solute, the space between the solvent particles is filled. As a result, no more solute particles can dissolve in the solvent.

Answer:

627.4 mmHg

Explanation:

From Gay-Lussac law:

$\frac{p1}{t1} = \frac{p2}{t2}$

p1 = 760 mmHg

t1 = 343 K

t2=283.15 K

$p2 = p1 \times \frac{t2}{t1}$

$p2 = 760 \times \frac{283.15}{343.0}$

$p2 = 627.4 \: mmhg$

Which of the following will decrease the percentage ionization of 1.0 M acetic acid, CH3CO2H(aq)?

arlik [135]

Answer: C. Adding concentrated HCL(aq)

Explanation:

HCl is an efficient acid that will increase the quantity of H+ in the solution and thus reduce the ionizing percentage of Ch3CO2H. The amount of ionization of the latter would be reduced by the addition of strong acid to a solution of weak acid.

What is the concentration of a solution with 2.00 moles of solute in 4.00 l of solution?

jarptica [38.1K]

Explanation:

Molarity is defined as the the number of moles present in a solution divided by volume in liters.

Mathematically, Molarity = $\frac{/text{no. of moles}}{volume in liter}$

As it is given that number of moles present into the solution are 2.00 moles and volume is 4 liter. Therefore, calculate the molarity of solution as follows.

Molarity = $\frac{/text{no. of moles}}{volume in liter}$

= $\frac{2.00 moles}{4.00 L}$

= 0.5 M

Thus, we can conclude that the concentration of given solution is 0.5 M.
