Zn(CN)2 Ksp (30°C) = 7.30 x 10-12 AgSCN Ksp (30°C) = 5.90 x 10-11 CL chose to investigate the solubility equilibrium of this salt and determine its identity. To a 100.0 mL distilled water at room temperature, CL added the unknown reagent until it no longer dissolves. After letting the mixture stand for 15 mins, she filtered and collected the filtrate in another beaker. From this, a 20.00 mL aliquot was drawn and was titrated with 10.20 M of 5.00 x 10-4 M HCl to reach the phenolphthalein endpoint. A. Let X be the titratable species from the dissolved salt. Determine the concentration of X from the titration data. B. Based on the results of CL's experiment and the provided constants, what is the likely identity of the unknown salt? Show complete solutions to support your answer.
Ionic Equilibrium
Chemical equilibrium and ionic equilibrium are two major concepts in chemistry. Ionic equilibrium deals with the equilibrium involved in an ionization process while chemical equilibrium deals with the equilibrium during a chemical change. Ionic equilibrium is established between the ions and unionized species in a system. Understanding the concept of ionic equilibrium is very important to answer the questions related to certain chemical reactions in chemistry.
Arrhenius Acid
Arrhenius acid act as a good electrolyte as it dissociates to its respective ions in the aqueous solutions. Keeping it similar to the general acid properties, Arrhenius acid also neutralizes bases and turns litmus paper into red.
Bronsted Lowry Base In Inorganic Chemistry
Bronsted-Lowry base in inorganic chemistry is any chemical substance that can accept a proton from the other chemical substance it is reacting with.
