Potassium nitrate could also be obtained from store-bought black powder, simply by dissolving black powder in boiling water and filtering out the sulfur and charcoal.
Rather than waste either the sodium or the potassium we place the special nitrate resin on top of regular softening resin and along with removing the nitrates and sulfates we also soften the water with the same amount of salt being used.
The intermediate stage in the history of cooling foods was to add chemicals like sodium nitrate or potassium nitrate to water causing the temperature to fall.

Soil pH was affected by N source, with the potassium and sodium fertilizers increasing pH of the surface centimeter of soil and ammonium nitrate and ammonium sulfate reducing pH compared to the control value of 5.
