- Unpolluted rain water has a pH of about 5.5. Acid rain has been shown to have a pH as low as 3.0. Calculate the [H+] ratio of acid rain to unpolluted rain.arrow_forwardCommon Acids and Bases Use the data in Table 18.8 to answer the following questions. Which substance is the most basic? Which substance is closest to neutral? Which has a concentration of H+=4.01010M ? Which has a pOH of 11.0? How many times more basic is antacid than blood?arrow_forwardFigure 14.3 shows the pH of some common solutions. How many times more acidic or basic is each of these compared with a neutral solution? (a) Black coffee (b) Household ammonia (c) Baking soda (d) Vinegararrow_forward
- Draw a curve similar to that shown in Figure 14.23 for a series of solutions of NH3. Plot [OH-] on the vertical axis and the total concentration of NH3 (both ionized and nonionized NH3 molecules) on the horizontal axis. Let the total concentration of NH3 vary from 11010M to 1102M.arrow_forward. Calculate the pH corresponding to each of the pOH values listed, and indicate whether each solution is acidic, basic, or neutral. a. pOH = 4.32 b. pOH = 8.90 c. pOH = 1.81 d. pOH = 13.1arrow_forwardWhich property is not generally associated with acids? sour taste volatility ability to neutralize bases ability to dissolve metalsarrow_forward
- A table wine has a pH of 3.40. What is the hydronium ion concentration of the wine? Is it acidic or basic?arrow_forwardConsider two beakers of pure water at different temperatures. How do their pH values compare? Which is more acidic? More basic? Explain.arrow_forwardClassify each of the following as a strong or weak acid or base. a NH3 b HCNO c Mg(OH)2 d HClO3arrow_forward
- Hydrogen, H2S, and sodium acetate, NaCH3CO2 are mixed in water. Using Table 16.2, write a balanced equation for the acid-base reaction that could in principle, occur. Does the equilibrium lie toward the products or the reactants?arrow_forwardThe nickel(II) ion exists as [Ni(H2O)4]2+ in aqueous solution. Why is this solution acidic? As part of your answer, include a balanced equation depicting what happens when [Ni(H2O)6]2+ interacts with water.arrow_forwardThe pH of a sample of gastric juice in a persons stomach is 2.1. Calculate the pOH, [H+], and [OH] for this sample. Is gastric juice acidic or basic?arrow_forward
