in acid base titration an acid neutralized by a base or a base is neutralized by acid (both are neutralized by each other).
one common reaction is
in titration we fill burette with either acid or base and and take other in flask.
when we start adding solution from burette to flask, neutralization starts. at the ponint of complete neutrlization all the acid / base neutralized base /acid.
this point is when the content of flask or beaker consists of only water, salt and trace of indicator
thus answer is point of neutralization.
fecl₃ + 3 naoh → 3 nacl + fe(oh)₃
explanation:to balance a chemical reaction, we should maintain the stichiometry of all elements.also, we should demonstrate the conservation of mass that states "the mass doe not destroyed or created from nothing but it can transferred from form to another one".thus, by balancing the chemical reaction we are applying the conservation of mass.that in our example, the number of atoms of each element in the reacting and products sides must be equal.
fe is 1.0 atom in both sides.
na, cl, o, and h are 3.0 atoms in both sides.and thus the mass is conserved by balancing the chemical reactionc.
answer: measure the volume of that compound which 56.17 ml for 100 grams of that compound.
density is defined as mass present in unit volume of the substance .
density of the new liquid compound = 1.78 g/ml
in future if we wanted to to 100 gram of this compound without measuring its mass on the balance. what we can do is we can calculate its volume which we will require in a reaction with the of density.
so, instead of measuring the mass of the compound we can directly measure the volume of that compound which 56.17 ml for 100 grams of that compound.
