It is hard to tell sugar and salt mixture apart by merely glancing or touching. I wish I could master the art of segregating them without any arduous chemical process.
According to wikiHow, one may assess the grain sizes of salt and sugar. But they too, acknowledge that table salt and granulated sugar do look very similar; the differences in these 2 is minute.
Option 2: Acquire a sieve sized in between the 2 grain sizes so as to let the salt through. However, this method is clearly not fool proof since not all salt and sugar grain is of the same size. A salt granule could mask itself.
The best way to separate salt and sugar is by adding absolute alcohol to the mixture as only the sugar will dissolve, salt is insoluble in alcohol. Then after, proceed to evaporate or boil off the sugar and alcohol solution and you will be left with salt.
Much like in life, it requires more than looking or tactility to tell between genuine and the pseudo. It takes time, takes processes and occurrences. I once more wish I could distinguish them easily.
Then again, as much as I am grateful for the sugars in my life, excessive amount of sugar isn't all that good for the health. Salt heightens the sweetness of sugar; it teaches me to appreciate sugar better. More importantly, salt, to a moderate amount, does good to the body too.
As such, I am grateful for both the sugar and salt in my life. Sugar provides a sense of joy, while salt is vital for personal growth.
