Is Mg(OH)2 sparingly soluble or insoluble?Watch
However, the specification saysthat Mg(OH)2 is sparingly soluble.
What would I write in the exam to get the mark?
i.e. 156250 cm3 of water is need to dissolve 1 g
Sigma Aldrich say this:
Hmm, that didn't copy and paste well, here's a link: http://www.sigmaaldrich.com/united-k...olubility.html
i.e. Mg(OH)2 is practically insoluble.
If you have a saturated solution, it would have a pH of around 10.34.
Pro tip: always go with the specification.
