WebAboutTranscript. The pH of a salt solution is determined by the relative strength of its conjugated acid-base pair. Salts can be acidic, neutral, or basic. Salts that form from a strong acid and a weak base are acid salts, like ammonium chloride (NH4Cl). Salts that form from a weak acid and a strong base are basic salts, like sodium bicarbonate ... Weba series of saturated salt solutions is one way to achieve the desired humidity results. The appended table provides humidity fixed points ranging from 10 to 90 % relative humidity for the indicated saturated salt solutions. Generally speaking, humidity greater than 90 % is not used in thermal analysis experiments due to the risk of condensation.
