Disodium hydrogen phosphate na-atụfu ngwa ngwa molekul ise nke mmiri kristal iji mepụta heptahydrate (Na2HPO4.7H2O). Ihe ngwọta mmiri bụ ntakịrị alkaline (PH nke ngwọta 0.1-1N bụ ihe dịka 9.0). Na 100 Celsius C, mmiri kristal na-efunahụ ma ghọọ mmiri na-ekpo ọkụ, na 250 Celsius C, a na-ere ya na sodium pyrophosphate. Uru pH nke 1% ngwọta mmiri bụ 8.8 ~ 9.2; mmanya na-egbu egbu. Gbazee na 35.1 ℃ wee tụfuo mmiri kristal 5.
