Remarks on result:
other: 44-49% w/w
Details on results:
No information is available on pH for the quoted solubility and the pH dependence is thus not known. However, given the high solubility it is not considered important. Nevertheless, given the dissociation constant (pKa ca. 5) lower solubility is anticipated at lower pH close to the pKa.

25 °C

Additional information

On a Weight of Evidence approach the substance is considered to be very soluble (> 10000 mg/L) in water.

Values from the CRC Handbook (peer reviewed literature) indicate water solubility is 783 - 970 g /L at 25°C and unknown pH.

Campbell and Marsh (1959) give a water solubilitiy of ammonium bromide of 44.08 % at a temperature of 25°C.

Smith and Eastlack (1916) reported several solubilities at increasing temperature and unknown pH:
