The volume Naoh is required to reach the equivalent point is L.
Equivalent point is the point in the chemical reaction when there is acid or base to neutralize the solution. It is also known as stoichiometric point. The moles of the titrant is equal to the moles of the unknown concentration in the titration.
The volume of the nbr solution is 0.20m and the concentration of nbr is 10ml. and concentration of the Noah is 0.10.so, here C1 is 0.20m and v1 is 0.010l and C2 is 0.10m .
so putting all the value sin the expression,
C1 V1 = C2 V2
where C1 is the concentration of the acid ,c2 is the concentration of the base,V1 is the volume of the acid and V2 is the volume of the base.
V2=C1. V1 / C2
= 0.20 .0.010 /0.10
= L of Naoh.
