Answer: The grams of solute required to make 250 g of 0.10% MgSO_4 is 0.25 g

Explanation:

To calculate the mass percent of element in a given compound, we use the formula:

\text{Mass percent}=\frac{\text{Mass of solute}}{\text{Mass of solution}}\times 100

Given :

Mass of solution = 250 g

Mass percent of solution = 0.10%

Putting in the values:

0.10=\frac{\text{Mass of solute}}{250g}\times 100

{\text{Mass of solute}}=0.25g

Answer:

= 0.25 g MgSO4

Explanation:

0.10% implies that the solution will contain 0.1 g of magnesium sulfate, for every 100 mL of solution.

Therefore;

= 250 g × 0.1 g/100 mL

= 0.25 g MgSO4

g If a small amount of a strong acid is added to a buffer made up of a weak acid, HA, and the sodium salt of its conjugate base,
ikadub [295]

Answer:

Explanation is in the answer

Explanation:

The pH of the buffer solution does not change appreciably because the strong acid (free H⁺) reacts with conjugate base of buffer producing more weak acid. pH formula of buffers is (Henderson-Hasselbalch formula):

pH = pKa + log ( [A⁻] / [HA] )

The addition of strong acid decreases [A⁻] increasing [HA]. pH change just in the log of the ratio of [A⁻] with [HA], that is a real little effect over pH of the buffer solution.
