a) What mass of strontium nitrate (Sr(NO3)2) would be required to prepare 2.000 L of a 0.0180 M aqueous solution of this salt? (b) Calculate the mass percent of Sr(NO3)2 in this solution, assuming the density of the solution is 1.000 kg/L. c.) A 15.0 g sample of anhydrous sodium sulfate, Na2SO4, is dissolved in 4.83 L of water. The molar mass of sodium sulfate is 142.1 g/mol. Use the equation given to calculate the molality (m) of the solution, in mol/kg.For this situation, assume the density of water is 1.00 g/mL.
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.
