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.

Once upon a time, Tricia and her sister Jillian are doing titration to assess the molarity of the sample's total acid content. Using the pH measurements to report acidity, they were ordered to study a clear aqueous solution of an unknown monoprotic acid. They decided to use two methods of experiments to gather essential data for their Chemistry Class. The first method is through a pH strip. To estimate the pH of the sample, Tricia used a pH strip. Tricia collected 1 mL of the sample, which came out to have a pH of around 3.3. Furthermore, Tricia made a new setup in which 1 mL of the same sample was diluted with 9 mL of water, and the pH taken was now around 3.8. The second method is Titration, and Jillian used this method. Jillian prepared a 10 mL aliquot of the sample and diluted it with 25mL of distilled water. After this, Jillian added 2 drops of phenolphthalein, and it was titrated 3.54 mL of 0.048 mmol standardized NaOH to the endpoint. With this, answer the following questions.1.…

Will 260.0 milligrams of calcium carbonate raise the pH of 75.0 milliliters of stomach fluid from a low pH of 1.00 into the normal pH range of 1.50-3.50? In the last discussion, you calculated that 260.0mg of calcium carbonate is 0.2600g of calcium carbonate. The next step is to figure out the formula of calcium carbonate and to calculate the molar mass of calcium carbonate in grams per mole. Submit a reply that that tells how you decided to approach the problem and shows the work that results in an answer. Use correct units and significant figures and correct symbols for elements and math. In addition, select another student's explanation that makes sense to you and reply with a comment about the insight you gained from their answer. Calcium carbonate is an ionic compound. Ionic nomenclature is in section 2.8. Molar mass is described on page 74 in section 2.8 of the textbook.
