A metal forms the fluoride MF3. Electrolysis of the molten fluoride by a current of 3.86 A for 16.2 minutes deposits 1.25 g of t
larisa86 [58]

<u>Answer: </u>The molar mass of the metal is 96.45 g/mol

<u>Explanation:</u>

The fluoride of the metal formed is MF_3

The oxidation half-reaction follows:

M\rightarrow M^{3+}+3e^-

Calculating the theoretical mass deposited by using Faraday's law, which is:

m=\frac{M\times I\times t(s)}{n\times F}       ......(1)

where,

m = actual mass deposited = 1.25 g

M = molar mass of metal = ?

I = average current = 3.86 A

t = time period in seconds = 16.2 min = 972 s            (Conversion factor: 1 min = 60 sec)

n = number of electrons exchanged = 3mol^{-1}

F = Faraday's constant = 96500 C

Putting values in equation 1, we get:

1.25g=\frac{M\times 3.86A\times 972s}{3mol^{-1}\times 96500 C}\\\\M=\frac{1.25g\times 3mol^{-1}\times 96500 C}{3.86A\times 972s}\\\\M=96.45g/mol

Hence, the molar mass of the metal is 96.45 g/mol

In the first step of the reaction, which compound is the limiting reagent: sodium hydroxide or the nucleophile
anastassius [24]
Since the nucleophile is the actual attacking molecule or molecule that starts the reaction and allows for further steps in the mechanism to occur, it is the limiting reagent, as based on the amount of the nucleophile you have, the reaction will tend to proceed until you run out. The excess would be the sodium hydroxide, it is union part of the solution.
