kirill [66]

Answer: Option (b) is the correct answer.

Explanation:

Buffere is defined as the solution to whom when an acid or base is added then it resists any in change in pH of the solution.

This is because a buffer has the ability to not get affected by the addition of small amounts of an acid or a base. So, basically it keeps the concentration of both hydrogen ions and hydroxides equal. As a result, it helps in maintaining the pH of the solution.

And, the capacity of a buffer solution to resist the change is known as buffer capacity.

Thus, we can conclude that buffering capacity refers to the extent to which a buffer solution can counteract the effect of added acid or base.

masya89 [10]

Answer: In this case, you can estimate that the solubility of potassium nitrate in water at  

60

∘

C

is equal to about

solubility  

≈

110 g / 100 mL water

−−−−−−−−−−−−−−−−−−−−−−−−−−−−−−−−  

This tells you that a saturated solution of potassium nitrate will hold about  

110 g

of dissolved salt, i.e. of dissociated salt, per  

100 mL

of water at  

60

∘

C
