硝酸钾固体物质的溶解度与溶质、溶剂的本性有关，通常溶质的结构与溶剂的结构相似时较易溶解，即所谓相似相溶原理，它可解释部分事实。大多数固体物质的溶解度随温度升高而增大，温度对不同的物质影响不同，可根据物质溶解度与温度的关係作出溶解度曲线，利用溶解度曲线可找出在任何温度时，某物质的溶解度，也可利用溶解度曲线提纯、分离某些物质。固体物质的溶解度受压力影响较小。物质的溶解性溶解性溶解度（20℃）易溶大于等于10g可溶大于等于1g小于10g微溶大于等于0.01g小于1g难溶（不溶）小于0.01g锕、氨、铵物质化学式0°C10°C20°C30°C40°C50°C60°C70°C80°C90°C100°C氢氧化锕(III)Ac(OH)30.0022氨NH388.5705644.53426.520151187叠氮化铵NH4N31625.337.1苯甲酸铵NH4C7H5O220碳酸氢铵NH4HCO311.916.121.728.436.659.2109170354溴化铵NH4Br60.668.176.483.291.2108125135145碳酸铵(NH4)2CO3100氯酸铵NH4ClO328.7氯化铵NH4Cl29.433.237.241.445.850.455.360.265.671.277.3氯铂酸铵(NH4)2PtCl60.2890.3740.4990.6370.8151.442.162.613.36铬酸铵(NH4)2CrO42529.23439.345.35976.1重铬酸铵(NH4)2Cr2O718.225.535.646.558.586115156砷酸二氢铵NH4H2AsO433.748.763.883107122磷酸二氢铵NH4H2PO422.739.537.446.456.782.5118173氟硅酸铵(NH4)2SiF618.6甲酸铵NH4HCO2102143204311533磷酸一氢铵(NH4)2HPO442.962.968.975.181.897.2硫酸氢铵NH4HSO4100酒石酸氢铵NH4HC4H4O61.882.7碘酸铵NH4IO32.6碘化铵NH4I155163172182191209229250硝酸铵NH4NO3118150192242297421580740871高碘酸铵(NH4)5IO62.7草酸铵(NH4)2C2O42.23.214.456.098.181422.427.934.7高氯酸铵NH4ClO41216.421.737.734.649.968.9高锰酸铵NH4MnO47.9磷酸铵(NH4)3PO426.1硒酸铵(NH4)2SeO496105115126143192硫酸铵(NH4)2SO470.67375.478818895103亚硫酸铵(NH4)2SO347.95460.868.878.4104144150153酒石酸铵(NH4)2C4H4O645556370.576.586.9硫氰酸铵NH4SCN120144170208234346硫代硫酸铵(NH4)2S2O32.15钒酸铵NH4VO30.480.841.322.42
