Actually most of the salts are insoluble in water. Not all the salts include chloride!!! And of those witch contain chloride, silver, led and mercury salts are insoluble!!! chemically speaking, not all salts are soluble in a particular solvent under normal conditions..
Table salt (NaCl) is soluble in water, but there are other salts such as lead chloride which are insoluble or only slightly soluble.oney is soluble in Water. Think of it this way: No matter how hot you make water, oil will not dissolve in it. But, if you make water hot and put in honey (think tea with hon â¦ ey) the honey will dissolve.
