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.
Answer:
The answer to the question is true.
Explanation:
it helps in when the kidney has used the needful nutrients been taken then the unwanted waste product it sends it to the nervous system then the nervous system passes the waste product to the bladder in form of urine
D electrons
a bond is not a physical material, it's an action
protons and neutrons are specific to that atom, and the amount doesn't change.
when atoms bond together, they share electrons to make themselves neutral
