氢氧化钠,化学式为NaOH,俗称烧碱、火碱、苛性钠,是一种具有很强腐蚀性的强碱,易溶于水,溶于水时放热,形成碱性溶液。氢氧化钠的溶解度随温度的升高而升高。氢氧化钠在不同温度下的溶解度具体如下:
温度(℃)&nbsp &nbsp &nbsp &nbsp 溶解度(g/100ml)
&nbsp0&nbsp &nbsp &nbsp &nbsp &nbsp &nbsp &nbsp &nbsp &nbsp &nbsp &nbsp &nbsp42
10&nbsp &nbsp &nbsp &nbsp &nbsp &nbsp &nbsp &nbsp &nbsp &nbsp &nbsp 51
&nbsp20&nbsp &nbsp &nbsp &nbsp &nbsp &nbsp &nbsp &nbsp &nbsp &nbsp 109
&nbsp30&nbsp &nbsp &nbsp &nbsp &nbsp &nbsp &nbsp &nbsp &nbsp &nbsp &nbsp119&nbsp
室温通常为25℃,所以其溶解度在109~119之间
