To complete the lab report, please answer the following questions. 1. Another way of testing for pH is to use pH paper. The pH paper is coated with a chemical that changes colors when immersed into the sample being tested. The color of the paper is then compared against a color chart that shows the colors associated with the different pH values. State one disadvantage of using pH paper instead of a pH meter. Answer: 2. The pH scale is a logarithmic scale. This means that the difference between each pH unit is really a factor of ten (in terms of actual magnitude of the acidity or basicity of the substance). If the pH of grapefruit juice is 3 (pH = 3), and the pH of beer is 5 (pH = 5), how many times more acidic is grapefruit juice than beer? 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.
