Science Buddies: "Ask an Expert"

Hello, Does anyone know the exact ratio of salt to water for experiments on which salt will conduct electricity best at different temperatures (How much salt is in a liter of water)?

This avoids wasting time and does not affect the experimental results. Thank.

Hi there,

In terms of making the water conduct electricity better, the more salt you add the better it will conduct electricity. This is because of the ions formed when table salt(NaCl) dissolves in water adds electrolytes into the water, which conduct electricity better. With standard DI(deionized) water, you can dissolve 357g of NaCl in one liter of water. This will lead to the most possible electrolytes in the water while avoiding over saturation of the water. Hope this helps.
