Barium reacts with a polyatomic ion to form a compound with the formula Ba(X). What would be the formula for a salt formed betwe
1 answer:
Answer:
Explanation:
Common ionic charge exhibited by Barium is +2.
Compound formed by Barium and polyatomic ion (X) is Ba(X).
Therefore, ionic charge on polyatomic (X) should be -2 in order to Ba(X) to be neutral.
Common ionic charge exhibited by sodium is +1.
If sodium forms salts with (X), Then, two atoms of sodium will be needed in order to make it neutral. in compounds or salts, no. of atoms are represented as subscripts. Therefore, formula of salts betweem sodium and polyatomic ion should be

Answer:
Explanation:
Hello,
In this case, since the reaction between potassium hydroxide and nitric acid is:
We can see a 1:1 mole ratio between the acid and base, therefore, for the titration analysis, we find the following equality at the equivalence point:
That in terms of molarities and volumes is:
Thus, solving the molarity of the base (KOH), we obtain:
