The correct answer is letter a, whereas, carrying capacity
in captivity increases population size. It is because the carrying captivity is
the one responsible for having a maximum population size in which will help in
sustaining the necessities that the species need in the environment in which
makes it responsible for the population size to increase depending on its
capacity. The correct answer is letter a.
Answer:
The best definition is: "Buffer capacity is the amount of acid or base that can be added to a buffer without destroying its effectiveness"
Explanation:
A buffer is a solution that is somewhat resist to pH changes by reacting with acids and bases that may be added into the solution. It's capacity is the amounto of acid or base that can be added into solution without much change in pH.
So the best definition is: "Buffer capacity is the amount of acid or base that can be added to a buffer without destroying its effectiveness"

The equation described by the kb value is 5.21 x 
.
The potential of Hydrogen is what pH is formally known as. The negative logarithm of the concentration of H+ ions is known as pH. Thus, the definition of pH as the amount of hydrogen is provided. The hydrogen ion concentration in a solution is described by the pH scale, which also serves as a gauge for the solution's acidity or basicity.
Assuming PO₄³⁻ (the phosphate anion).
PO₄³- + H₂O ==> HPO₄²⁻ + OH⁻
Kb = [HPO₄²⁻][OH⁻] / [PO₄³⁻]
We can find the [OH⁻] from the pH of 12.70.
pH + pOH = 14
14.0 - 12.7 = 1.3 = pOH
[OH] = 1x
[OH-] = 5.0x
M
[HPO₄²⁻] = 5.0x M
Kb = (5.0x)2 / 0.48
= 2.5x / 0.48
Kb = 5.21 x
