Was this dissolving process exothermic or endothermic? Draw a diagram of the experimental set-up and label all of the "equipment gunmen , DATA TABLE: . Question: Lab 5. 1. Le Chatelier's principle predicts that an addition of heat to an endothermic reaction (heat is a "reactant") will shift the reaction to the right (product side). Each type of hydrate traps water in its own unique way, but heating a hydrate will release the Experimental value - theoretical value Theoretical value x 100 6. To write the formula of a hydrate, the compound is written followed by 0 and then the Put the molecular mass of all the water molecules and divide that by the total mass of the entire hydrate and multiply by 100. After heating, the anhydrous sample had a mass of 1.8820 grams. upon heating, a hydrate decomposes and produces an. Accessibility StatementFor more information contact us atinfo@libretexts.org. Given the formula mass of the unknown anhydrous salt, it is possible to determine the water of crystallization and, therefore, the formula of the hydrate salt. formula (or multiplication sign) indicates that the waters are there. Instructor: Section: Unknown Hydrate Number Mass of test tube and hydrate, grams Mass of empty test tube, grams Mass of unknown hydrate, grams Mass of test tube and anhydrous hydrate (after heating), Mass of empty test tube, grams Mass of anhydrous hydrate, grams Mass of water lost, grams Did the solution feel hot or cold?

What is the difference between a hydrated compound and an anhydrous one? safety glasses, matches/lighter. 8 + 9 +10 / 3 = 9% Your blue-green copper sulfate has several water molecules attached to it, while your friend's copper sulfate is anhydrous (no water attached). The name of the compound is cobalt (II) chloride hexahydrate and its formula is \(\ce{CoCl_2} \cdot 6 \ce{H_2O}\). 2. (Convert mass to moles.) (Hint: Have you seen this compound before? Multiplying
Finding the experimental percentage of water in a hydrate is found by ___ the ___ before and after heating. We can Record the number of that sample on your Data Table. The mass of water evaporated is obtained by subtracting the mass of the anhydrous solid from the mass of the original hydrate (\ref{3}): % H20 ,= (mass H20/ mass of hydrate) x 100 , What is a hydrate? What is a hydrate? After heating, the anhydrous sample had a mass of 1.8820 grams. ~; ,., a A a 1. It is often common for crystalline structures to contain water, and so in this experiment, it will be determined if this unknown is one of the many solid chemicals that are classified as hydrates. the slower the object. sheet and clearly show all calculations.
