solubility of salt in water experiment

Measure out a teaspoon of table salt and add it to the cup of water and stir using a coffee stirrer. 0000001276 00000 n The table below provides information on the variation of solubility of different substances (mostly inorganic compounds) in water with temperature, at one atmosphere pressure.Units of solubility are given in grams per 100 millilitres of water (g/100 ml), unless shown otherwise. <]>> 0000005523 00000 n 2 0 obj )�!��@�_��e8zoG�)��"�[��JA�����v��G���mƆ��Z���ـ �iQ�u*$��X��3LeS�T��4�)�T ��!
