The concentration of the HCl solution is 0.047 M.
Explanation:
Data given about acid and base:
volume of acid Vacid = 46.9 ml
molarity of acid =?
volume of the base (NaOH) = 16.4 ml
molarity of the base = 0.135 M
To know the concentration of the acid in this reaction, the formula used in titration is used. It is
Macid X Vacid = Mbase X Vbase
the formula is rewritten as:
Macid =
putting the values in the equation:
Macid =
= 0.047 M
the concentration of the acid i.e HCl in the solution is of 0.047 M.
The symbol is for phosphorus having atomic number 15. That means it has
in its neutral state.
The given symbol has a -3 charge that means it has gained 3 electrons so, the number of electrons in the
is:
. The number of protons will remain same that is the number of protons = 15.
So, the ion has
that gives
charge on the
ion.
So, the answer is .
