250毫升5mol/L氢氧化钠溶液怎么配制? - 知乎
5mol/L×0.25L×40.00g/mol=50g. 根据描述大概率不是标准液,粗配可以用一个250mL的烧杯,用 台秤 称取50g的氢氧化钠于烧杯中,加水溶解,用滤纸盖上,等温度降至室温在加水至250mL刻度线。 当然你也可以用 容量瓶 但是没必要,如果想要得到精确浓度必须要用标定,所以配制出大概5mol/L就可以。 不过 滴定 最好5mol/L的氢氧化钠溶液精确稀释10倍再去标定。 标准液需要先配饱和溶液过夜,吸取上清液用容量瓶配置,也逃不过标定。 你这不像是 标准滴定溶液 (标准滴 …
Sodium Hydroxide Solution, 5.0M, Chem-Lab | Fisher Scientific
Sodium Hydroxide Solution, 5.0M, Chem-Lab is a strong base and is highly caustic. It is used to increase the alkalinity of a mixture, to neutralize acids and to make sodium salts. One liter of the solution includes 5.0mol (200g) of NaOH.
Dissolve 20.0g of NaOH pellets in 80ml of deionised water in a beaker. When cooled, bring the final volume to 100ml. Transfer the solution to a glass bottle and label your reagent.
