The acidity of a solution is measured by its pH. If Ht represents the concentration of hydrogen ions (in moles/liter) in the solution, the pH is defined by pH - log Ht| Based on careful measurements and calculations, a chemist examines two solutions and asserts: "The hydrogen ion concentration of Solution A is 65.86% greater than the hydrogen ion concentration of Solution B." If the pH of solution B is 10.00, determine the pH of Solution A. Report your answer to two decimal places. Solution A has pH equal to Number (Report to the nearest 0.01)

Using the data below, make a graph of the Volume vs. Pressure of a container, with volume being the independent variable. Is the relationship linear? If it is not, make a graph of Volume vs. 1/pressure. What would the pressure of the container be if the volume were 2.4 L? Show your calculation.

Each of the four flasks below contains the same volume of .10 M aqueous acid. All four acids are monoprotic, meaning that each acid molecule gives up one H+. The pH of each solution is as indicated. Flask A: pH=1.1 Flask B: pH=2.4 Flask C pH= 2.9 Flask D: pH=5.1 How much strong base is required to neutralize the initial amount of acid? A. All four solutions will require the same amount of base because they all contain acid of the same concentration B. The solution of pH=1.1 will require the most base since it is the strongest acid and has the highest concentration of H+ C. Neither (A) nor (B) is correct.

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.
