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:Well-known examples are sodium hydroxide (NaOH) with OH- as the polyatomic anion, calcium carbonate (CaCO3), and ammonium nitrate (NH4NO3), which contains two polyatomic ions: NH+ and NO3-. ... The properties of compounds containing polyatomic ions are very similar to those of binary ionic compounds.
Explanation:
Answer:
The volume of base was required for the titration is 13,53mL
Explanation:
In a titration of an acid (HX) with a base (YOH), the reaction of neutralization is:
HX + YOH → YX + H₂O
In the burette you are adding base until all HX reacts. The addition of base is in volume.
If in the beginnig, the volume that you read of base is 2,94mL and at the endpoint you read a volume of 16,47mL. The volume you spent in the titration that is the same volume of base you required for the titration is:
16,47mL - 2,94mL = <em>13,53mL</em>
