Consider a situation in which acid rain has heavily polluted a lake to a level of pH 4. An unscrupulous chemical company dumps some acid into the lake illegally. Assume that the lake contains 250 million gallons of water and that the company dumps 250,000 gallons of acid with pH 2. Complete parts (a) through (d) below. a. What is the hydrogen ion conentration, [H*], of the lake polluted by acid rain alone? (Type your answer using exponential notation.)

True or false? 1. Arrhenius' definition states that an acid is a substance that increases the concentration of H3O+ when added to water. 2. The Brønsted-Lowry definition of acid required the formation of H3O+ in solutions. 3. At 100°C, the Kw is 51.3 × 10^-14. At this temperature pure water : a) neutral, b) is slightly basic, c) has a pH of 6.14 or d) has a pOH of 7.86

10. The active ingredient in many toilet bowl cleaners is simply hydrochloric acid. Hydrochloric acid is particularly good at removing rust stains and hard water deposits. One particular brand uses hydrochloric acid at a concentration of 5.800 M. A. B. What is the equilibrium concentration of H₂O* of a pH = 5.172 solution? Please provider your answer below. What is the pH of the 5.80 M HCl solution? Please provider your answer below. ☐☐ S + 00 S C. To what volume would 35.00 mL of this brand have to be diluted for the final solution to have a pH = 1.20? mL Please provider your answer below. M $

pH Level In chemistry, the pH of a substance is defined as pH = − log log [H+] where H+ is the hydrogen ion concentration, in moles per liter.

The pH of a neutral solution is higher than 7 at 37 degrees celsius B. The pKw for water is larger at 37 degrees celsius than at 25 degrees celsius C. The pOH of a .01 M KOH solution is lower at 37 degrees celsius than at 25 degrees celsius D. The pH of a .01 M HNO3 solution is higher at 37 degrees than t 25 degrees E. At 37 degrees celsius, pH + pOH < 14 WHta is the correct answer and why?

Four solutions of an acid dissolved in water are sketched below, as if under a microscope so powerful individual atoms could be seen. The same volume of solution is shown in each sketch. Rank the solutions by the strength of the dissolved acid. That is, select 1 under the solution of the strongest acid, 2 under the solution of the next strongest acid, and so on.
