For this reaction, equilibrium constant is Keq, A: The equilibrium between the soluble ions and insoluble salt can be described by the solubility, A: To calculate maximum dissolved [Mg2+] , PubChem . Which forms first, solid AgBr or solid AgCl? It can be clearly seen that one mol of AgNO3 gives 1 mol of AgBr. This is an example of a phenomenon known as the common ion effect, which is a consequence of the law of mass action that may be explained using Le Chtelier's principle. Substitute the value of the molar mass of AgBr in the relation given below to evaluate the mass of AgBr as shown: Substitute the values in equation (2) for evaluating the mass of AgBr in grams as: Copyright 2023 StudeerSnel B.V., Keizersgracht 424, 1016 GC Amsterdam, KVK: 56829787, BTW: NL852321363B01, Give Me Liberty! [Ag +] 2 = 5.0 x 10 -13 Taking the square root of both sides of this equation gives the equilibrium concentrations of the Ag + and Br - ions. Ksp for AgBr is 5.0 10. The atomic mass number, which is distinct from the atomic mass and the atomic weight, is 9. Dwusif Uq59v_b$Flv5cYwk.6|thACV%cYn@[\h^s{FIh Qt4b-)}}`Yd>e_8S5x|B*Ob.# 35,000 worksheets, games, and lesson plans, Spanish-English dictionary, translator, and learning, a Question Using the chemical formula of the compound and the periodic table of elements, we can add up the atomic weights and calculate molecular weight of the substance. The balanced equation's ratios are used in this instance. (molar mass of AgBr = 187.77 g/mole) MgBr2 (aq) + 2AgNO3 (aq) --> 2AgBr (s) + Mg (NO3)2 (aq) 0.985 g 0.493 g 1.97 g 986 g none of these This problem has been solved! Arrhenius acid act as a good electrolyte as it dissociates to its respective ions in the aqueous solutions.
