Answer:
the answer to this question is 2 kilogram/cubic meter
Explanation:
Answer:
When pH = pKa, the ionizable compound in question (either acid or base) will be half protonated and half deprotonated
Explanation:
A convenient way of expressing the relative strength of an acid is by the value of its pKa, which makes it easy to see in small changes in pKa the changes associated with large variations in Ka. Small pKa values are equivalent to large Ka (dissociation constant) values, and as pKa decreases, the strength of the acid increases.
An acid will be stronger the lower its pKa and in a base it happens the other way around, which is stronger the higher its pKa.
Those dissociation constants are not fixed, they depend on other variables. For example, the dissociation constant changes at different temperatures. However, it maintains its value at the same temperature, before changes in the concentration of any of the species or even under the action of a catalyst.
