Your Cupric Sulfate Hydrate may be the monohydrate with one mole of water attracted to the cupric sulfate. The water present in the latter case is called water of hydration or water of crystallization. 1. A student collects the data in the table below. Empirical Formula Lab Report. f��ˉ�ao�.b*lI�r�j)�,l0�%��b� magnesium sulphate MgSO 4.7H 2 O. So if water is one of your reactants and you think about general chemistry, Le Chatelier's principle, how do you shift in equilibrium? A small portion of all water absorption occurs in the stomach and the colon (Shaffer and Thomson 1994): the small intestine absorbs 6.5L/day, whereas the colon absorbs 1.3L/day.These amounts correspond to the water ingested daily, in addition to the water … Mass of crucible + cover + hydrate: 22.326g. We will then accurately determine the weight of the anhydrous barium chloride. trailer << /Size 579 /Info 532 0 R /Root 536 0 R /Prev 146882 /ID[<19b078ee5e8f43ba2c47f05e5e0b1686>] >> startxref 0 %%EOF 536 0 obj << /Type /Catalog /Pages 534 0 R /Metadata 533 0 R /Outlines 10 0 R /OpenAction [ 538 0 R /XYZ null null null ] /PageMode /UseNone /PageLabels 531 0 R /StructTreeRoot 537 0 R /PieceInfo << /MarkedPDF << /LastModified (D:20010904130332)>> >> /LastModified (D:20010904130332) /MarkInfo << /Marked true /LetterspaceFlags 0 >> >> endobj 537 0 obj << /Type /StructTreeRoot /ClassMap 22 0 R /RoleMap 24 0 R /K [ 320 0 R 321 0 R ] /ParentTree 479 0 R /ParentTreeNextKey 4 >> endobj 577 0 obj << /S 57 /O 160 /L 176 /C 192 /Filter /FlateDecode /Length 578 0 R >> stream Hydration in chemistry is the attachment of water molecules to the molecule of … Hydration Lab.

What is a hydrate? In this lab we will take a hydrated compound and accurately determine the initial mass. Purpose: 1) Dehydrate Epsom salt using chemistry procedures and determine the amount of water it contains 2) Use your math skills to determine the mole ratio, or how many moles of H 2 O there are compared to moles of MgSO 4 (Epsom salt) 3) Compare your lab determined mole ratio to the real mole ratio on the box of Epsom salt. This is known as 'water of crystallisation', and the 'hydrated' form of the compound. Crystal salts containing water of hydration are called hydrates. In some contexts, water of crystallization is the total mass of water in a substance at a given temperature and is mostly present in a definite (stoichiometric) ratio. 0000001586 00000 n 0000003103 00000 n When this occurs, the trapped water molecules are called water of hydration and they become an integral part of the crystal structure.
