A municipal water sample has 0.20 ppm Pb2+ by weight. The density of this sample is 1.00 g/mL. How many milligrams of Pb2+ is in 1 L of this water sample? 2 x 10-4 mg 2 x 10-1 mg 2 x 10-7 mg 2 x 10-10 mg What is the concentration of Cr3+ in a saturated solution of chromium (III) hydroxide (Ksp = 6.3 x 10-31)? You may ignore activity effects. 6.3 x 10-31 M 7.9 x 10-16 M 8.5 x 10-11 M 1.2 x 10-8 M
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.
