B. Straining liquid out of food
Answer:
protons and neutrons
Explanation:
The nucleus of the atom contains protons and neutrons. The electrons of the atom orbit the nucleus.
Answer:
pH = 5.58
Explanation:
Given that :
Citric acid is a triprotic acid with the formula
. Tripotic acids are acids that have the tendency to yield three protons per molecule during the phases of dissociation, therefore they have three pka.
For Citric acid; the pka values are:

So, the pH of sodiummonohydrogencitrate with the chemical formula
which can act as an acid and a base (i.e it is said to be amphoteric) can be calculated as :


pH = 5.58
Therefore, the approximate pH of a solution of sodium monohydrogencitrate = 5.58
