Calculation of Equivalent Weight of Metal Bromide

Metal chloride contains 71% chlorine. To calculate the equivalent weight of metal bromide, we need to use the concept of equivalent weight.

Equivalent Weight
Equivalent weight is the weight of a substance that reacts with or replaces one mole of hydrogen ions in an acid-base reaction or one mole of electrons in a redox reaction.

Calculation of Equivalent Weight of Metal Chloride

To calculate the equivalent weight of metal chloride, we can use the following formula:

Equivalent weight = Molecular weight / Valency

Metal chloride contains 71% chlorine, which means that the remaining 29% is the metal. We can assume that the metal is a monovalent metal, which means that its valency is 1.

Let us assume that the molecular weight of metal chloride is M. Then we can write:

0.71M = molecular weight of chlorine
0.29M = molecular weight of metal

Now we can substitute the molecular weight of metal and chlorine in the formula for equivalent weight:

Equivalent weight = M / 1 = M

Therefore, the equivalent weight of metal chloride is M.

Calculation of Equivalent Weight of Metal Bromide

To calculate the equivalent weight of metal bromide, we can use the same formula as before:

Equivalent weight = Molecular weight / Valency

The atomic weight of bromine is 80. Let us assume that the molecular weight of metal bromide is N.

Metal bromide contains 80/160 = 0.5 or 50% bromine by weight.

Therefore, we can write:

0.5N = molecular weight of bromine
0.5N = molecular weight of metal

Now we can substitute the molecular weight of metal and bromine in the formula for equivalent weight:

Equivalent weight = N / 1 = N

Therefore, the equivalent weight of metal bromide is N.

Conclusion

The equivalent weight of metal chloride is M, and the equivalent weight of metal bromide is N. Since we do not know the identity of the metal in these compounds, we cannot calculate their exact values. However, we can say that the equivalent weight of metal bromide is equal to its molecular weight, just like the equivalent weight of metal chloride.
