Acetylsalicylic acid (a monoprotic acid with MW = 180.16 g mol-1, Ka = 3.16 x 10-4) is the active ingredient in Aspirin, and is the only component that contributes to the acidity/basicity. A 1.50 g Aspirin pill was dissolved in 100. mL water, and a pH of 3.10 was measured. What is the percent composition (by mass) of acetylsalicylic acid in the Aspirin pill? %3D 41.8% 3.35% 7.54% 17.5% Consider the dissolution of the following salt, PbCl2(s) PbCl2(s) = Pb2*(aq) + 2 Cl (aq) Thermodynamic data for`this reaction at 298 K are provided below: AH° rxn = 26.2 kJ molT1 AS°rxn = -2.1 JK-1 mol1 What is the molar solubility of P6CI2(s) in mol L1? Determine whether a solution containing 5.0 × 10 2 mol L Pb2 (aq) and 3.0 × 10-2 mol L CF(aq) will precipitate or not. O 6.9 x 102 mol L; precipitate will not form O 6.9 x 102 mol L; precipitate will form O1.7 x 10 2 mol L precipitate will not form 1.7 x 10 2 mol L precipitate will form
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.
