How to distinguish and identify saline solutions from ethylene glycol solutions?
If I had to choose between the two, the simpler option is: it’s clear that frozen saline causes significant corrosion to the system pipes; it gives them a darker color and makes them dirtier (which means it’s not very reliable)； Second measurement: The viscosity of the ethylene glycol aqueous solution is relatively high ； Check it by hand at room temperature ； Specific gravity: The specific gravity of frozen saline is generally above 1.25, while that of ethylene glycol water solutions is not so high ； Fourth precipitation: Adding sodium carbonate or sodium bicarbonate in the laboratory causes the salt water to produce a white precipitate (calcium carbonate).

The difference is quite obvious; there’s no need to distinguish between them, right?
Not bad; theory and practice are combined
Yes, give it a try; the salty taste comes from calcium water
This is definitely an unsuitable approach. In a chemical plant environment, one should be careful about eating and drinking – how dare someone taste things there directly? Aren’t you afraid of dying from poisoning?
