Precipitation: in chemistry, precipitation is the process of removing one or more substances from a solution by adding reagents so that a precipitate (a solid that forms in a solution during a chemical.
To correctly determine the identities of two unknown cations in solution qualitative tests such as precipitation reactions and flame tests demonstrated the chemical principles of solubility and electron excitation the identity of the cations in unknown solution 1 were found to be ag + solutions. Thermodynamic prediction of precipitation reactions prelab assignment before coming to lab: read this lab handout thoroughly and then answer the pre-lab questions on the last page of lab 7 report sheet name thermodynamic prediction of precipitate rxns team no. Precipitate lab 1 for each compound, write the two ions that make it up (ex: ( k2cro4 = k+ cro42- ) 2 in each square, write the two new compounds that will form 3 cross out any compounds that you know will be soluble in water and therefore will not be precipitates verify with the rest of the class which combinations result in.

Precipitation reactions: a chemical reaction that involves the formation of an insoluble product (precipitate solid) is called precipitation reaction the reactants are soluble, but the product formed would be insoluble and confer your observations with your lab partner and work together to write the required chemical equations. During the first semester of my freshmen year, i had to hand in the lab report below after conducting a group experiment in chemistry class it was done in june, a few weeks before our final exams chemistry lab report ‘solubility rules and precipitation reactions’ 10221 soojung lee date of experiment: 2013. Answer key precipitation lab purpose: 1 identify the ions present in various aqueous solutions 2 combine solutions and identify the reactions that form precipitates 3 write balanced molecular equation, complete ionic equation, and a net ionic equation for each precipitation reaction materials: small test tubes various solutions procedure: 1 add 10-15 drops of the each reactant to a test.
