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_forwardGive the formula of the conjugate acid:(a) O²⁻(b) SO₄²⁻(c) H₂Oarrow_forward
- Hypochlorous acid, HOCl, is a weak acid having a pKa = 7.46. (a) Show the balanced chemical equation for the hydrolysis of water by OCl- (aq). (b) Compute the value of pKb for aqueous hypochlorite ion. (c) If [OCl-] = 0.050 M, then what is the pH of this aqueous solution? (a) (b) (c)arrow_forwardSodium hypochlorite solution is also known as bleach. It contains the hypochlorite ion ClO-. (a) Write an equation for the reaction between hypochlorite ion and ammonium ion. Label the acids and bases in the forward and reverse reactions. Identify the two conjugate acid-base pairs. (b) This equilibrium favors the reactants. Which of the acids is stronger and donates protons more readily?arrow_forwardThe pH scale for acidity is defined by pH – log10 H*| where |H*| is the concentration of hydrogen ions measured in moles per liter (M). (A) The pH of Drano is 13.3. Calculate the concentration of hydrogen ions in moles per liter (M). [H*] = M (B) The pH of rain water is 5.5. Calculate the concentration of hydrogen ions in moles per liter (M). [H*] = Marrow_forward
- A citrus tree can't get the nutrients it needs from the soil if its pH is above 6.5. (a) The hydrogen ion concentration of a soil sample is [H+] = 1.58 × 10−7 M. What is the pH of the soil? (Round your answer to one decimal place.)Is this soil suitable for citrus trees? Yes No (b) After the soil is amended, the pH is 5.6. Is the amended soil more acidic or less acidic than the original soil? more acidic less acidicarrow_forwardThe pH of a chemical solution is given by theformula pH = - log10 [H+ ] where [H+ ] is the concentration of hydrogen ions in molesper liter. Values of pH range from 0 (acidic) to 14 (alkaline).(a) What is the pH of a solution for which [H+ ] is 0.1?(b) What is the pH of a solution for which [H+ ] is 0.01?(c) What is the pH of a solution for which [H+ ] is 0.001?(d) What happens to pH as the hydrogen ion concentration decreases?(e) Determine the hydrogen ion concentration of an orange (pH = 3.5).(f) Determine the hydrogen ion concentration of human blood (pH = 7.4).arrow_forwardAcidity of a solution is determined by the concentration H of hydrogen ions in the solution (measured in moles per liter of solution). Chemists use the negative of the logarithm of the concentration of hydrogen ions to define the pH scale, as shown in the following formula. pH = -log (H) Lower pH values indicate a more acidic solution. (a) Normal rain has a pH value of 5.6. Rain in the eastern United States often has a pH level of 3.8. How much more acidic is this than normal rain? (Round your answer to two decimal places.) 63.10 times as acidic as normal rain (b) If the pH of water in a lake falls below a value of 5, fish often fail to reproduce.
