Answer:
21%
Explanation:
We have a mass of 210.0 g of NaCl and a volume of 1000 mL. To find the percentage solution (m/V), we would divide % percentage solution.
Answer:
Kindly check the attached picture for the diagram showing the titration curve.
Explanation:
The term "titration" is an important part of chemistry because it is being used in the Determination of the concentration is the unknown.
In this question, the titration is done between a polyprotic weak acid, that is Phosphoric acid (H3PO4) and a strong base, NaOH.
H3PO4 + OH^- -----------------> H2O + H2PO4^-.
H2PO4^-2 + OH^- ---------------> H2O + HPO4^2-
HPO4^- + OH^- ------------------> H2O + PO4^3-.
<span>Specific gravity is the ratio of the density of a substance to the density of a reference substance; equivalently, it is the ratio of the mass of a substance to the mass of a reference substance for the same given volume.</span>
