The quality assurance lab just received a shipment of three solutions. The lab manager asks you to verify the stock solutions and abel each bottle with the solution's hydrogen ion concentration, [H]. You first use the pH meter to determine the pH of each solution. Calculate the hydrogen ion concentration of solution #1, which has pH 2.25. Calculate the hydrogen ion concentration of solution #2, which has pH 7.25. Calculate the hydrogen ion concentration of solution #3, which has pH 10.75. (H*] = I [H*] = [H*] = M M 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.
