WebWater of crystallisation question: Calculate the number of moles of waters of crystallisation in tin (II) chloride given the mass of hydrated tin chloride an... A salt with associated water of crystallization is known as a hydrate. The structure of hydrates can be quite elaborate, because of the existence of hydrogen bonds that define polymeric structures. Historically, the structures of many hydrates were unknown, and the dot in the formula of a hydrate was employed to specify the composition without indicating how the water is bound. Per IUPAC's recommendations, the middle dot is not surrounded by spaces when indicating a chem… WebJul 20, 2024 · Example 14.1 (Q2) Purity calculation. Sodium chloride was prepared by neutralising sodium hydroxide solution with dilute hydrochloric acid. The solution was gently heated to evaporate most of the water and allow the salt to crystallise. The crystals were separated from any remaining solution and dried on a filter paper. ielts exam fee bangalore
