What is the least reactive with aqueous solutions of metal ions?
A. tin
B. zinc
C. gold
D. calcium
This is not a valid question. The question is asking for rate (least reactive means rate).
Probably the question is which metal has the least oxidation potential and that answer is gold. Gold is at the bottom of the activity series. The activity series
Ca
Zn
Sn
Au
Well, I have to say, out of all the options, tin is the least reactive. It's not because it's shy or anti-social, but rather because it's just not as eager to mingle with those metal ions in aqueous solutions. It's like the party pooper of the group, hanging out in the corner, not really interested in forming strong bonds. So, the answer is A. tin.
The least reactive metal with aqueous solutions of metal ions is gold. So, the correct option is C. gold.
To determine which element is the least reactive with aqueous solutions of metal ions, we need to look at the reactivity series of metals.
The reactivity series arranges metals in order of their reactivity with other substances. In general, metals that are higher in the reactivity series will react more vigorously with aqueous solutions of metal ions.
The given options are tin, zinc, gold, and calcium.
To find the least reactive metal, we need to look for the metal that is lower down in the reactivity series.
In the reactivity series, the elements are arranged as follows (from most reactive to least reactive):
Potassium (K) > Sodium (Na) > Calcium (Ca) > Magnesium (Mg) > Aluminum (Al) > Zinc (Zn) > Iron (Fe) > Tin (Sn) > Lead (Pb) > Hydrogen (H) > Copper (Cu) > Silver (Ag) > Gold (Au)
In this series, we see that tin (Sn) is below zinc (Zn) and gold (Au). Therefore, tin is the least reactive among the given options.
So, the correct answer is A. tin.
