Frequently Asked Questions

Q1

Is magnesium sulfate a compound or mixture?

Magnesium sulfate, MgSO4, is a colourless crystalline substance formed by the sulphur dioxide and air reaction of magnesium hydroxide.

Q2

Is magnesium sulfate soluble in alcohol?

Magnesium sulfate heptahydrate is a white, crystalline, or brilliant, usually needle-like crystals. It is readily soluble in water, in boiling water more easily soluble, and in alcohol virtually insoluble.

Q3

What is the hydrating formula for MgSO4

To obtain the mole ratio, divide the moles of water by moles of anhydrate. 5 H2O/1 mole MgSO4 moles = 5:1. To write the equation, use the mole ratio. Because for every 1 mole of MgSO4 there are 5 moles of H2O, the formula is 5H2O MgSO4.

Q4

What is magnesium sulfate heptahydrate used for?

One of the main applications of magnesium sulfate is to be used as a fertilizer in farming and gardening. For bath salts, magnesium sulfate is used.

Q5

How moles are calculated?

Use the molecular formula to calculate the molar mass; divide the weight of the compound by the compound’s molar mass measured in grams to obtain the number of moles.
