What is the formula for the expected precipitate? Fehling's sugar test. The following reaction is an example of a metathesis reaction: wont proceed since both potential products KOH and NaCl, In this experiment, you will watch videos where aqueous solutions will be mixed and you, will observe the formation of precipitates. Write the balanced equation for this reaction. If so, write the empirical formula of the precipitate. Need help with something else? D) water insoluble It is best to memorize these. If both products are soluble in water, then the ions will remain in solution and no reaction will take place; the formation of a. solid substance is the driving force for these reactions. answered 03/30/15, Highly qualified teacher for Chemistry and all levels of Algebra. biology. most sulfate salts are soluble = (aq) EXCEPT WITH lead, barium, etc then it would be (s). . Calculate the minimum volume of barium nitrate solution that was used. In order to balance the equation, we will make the coefficient of.
