I'd guess A or D, but my gut says A
Explanation:
It is known that the relation between pH and is as follows.
pH =
and,
Hence, first we will calculate the value of as follows.
=
= 4.75
Now, we will calculate the value of pH as follows.
pH =
=
= 4.75 + (-0.677)
= 4.07
Therefore, we can conclude that the pH of given solution is 4.07.
The periodic table of elements arranges all of the known chemical elements in an informative array. Elements are arranged from left to right and top to bottom in order of increasing atomic number. Order generally coincides with increasing atomic mass. The rows are called periods.
