QUESTION:
In each of the following pairs, indicate which has the higher concentration of \(\mathrm{I}^{-}\) ion:
(a) 0.10 M \(\mathrm{BaI}_{2}\) or 0.25 M KI solution,
(b) 100 mL of 0.10 M KI solution or 200 mL of 0.040 M \(\mathrm{ZnI}_{2}\) solution,
(c) 3.2 M HI solution or a solution made by dissolving 145 g of NaI in water to make 150 mL of solution.
ANSWER:Step 1 of 5
Given Data:
a)
\(Concentration\;of\;Ba{I_2} = 0.10\;M\)
\(Concentration\;of\;KI = 0.25\;M\)
b)
\(Concentration\;of\;KI = 0.10\;M\)
\(Concentration\;of\;Zn{I_2} = 0.10\;M\)
\(Volume\;of\;KI = 100\;mL\)
\(Volume\;of\;Zn{I_2} = 200\;mL\)
c)
\(HI\;solution's\;concentration = 3.2\;M\)
\(NaI's\;weight\;which\;dissolved\;in\;water = 145\;g\)
\(NaI\;solution's\;volume = 150\;mL\)
