The population will definitely decrease in size, because they become more vulnerable to predators and they'll lack a food source.
Explanation:
We have to calculate value.
It is known that at the equivalence point concentration of acid is equal to the concentration of anion formed.
Hence, [HA] =
Now, relation between and pH is as follows.
pH =
Putting the values into the above formula as follows.
pH =
4.23 = (as [HA] = )
= 4.23 (as log (1) = 0)
or, = 4
Thus, we can conclude that of given weak acid is 4.
Answer:
Two (2) types of ions
Explanation:
Metal ions (cations) and negatively charged ions (anions) of either chloride, carbonate, sulphides or hydroxides are present during the selective precipitation.
Majorly, the process determines the metal ions present by initiating precipitation as certain conditions.
