- Which solution is more acidic, one with a pH of 4 or a pH of 5? What is the concentration of H+ ions in each?A solution has a hydrogen ion concentration of 0.01 mol/L. What is its pH? What is its hydroxide ion concentration? Is it acidic, basic, or neutral? How does the hydrogen ion concentration of this solution differ from one with a pH of 1?Is a solution highly concentrated if it is saturated? Is a solution saturated if it is highly concentrated?
- The pHpH scale for acidity is defined by pH=−log10[H+] where [H+]is the concentration of hydrogen ions measured in moles per liter (M). A solution has a pH of 10.2. Calculate the concentration of hydrogen ions in moles per liter (M).What is the effect of adding a small amount of a strong acid or strong base to the acidity of a buffer? How would this compare to an unbuffered solution of the same acidity?Match each weak acid with the pH value at which it would buffer. pH 3 ammonium (PK, of 9.25) chloroacetic acid (pK, of 2.87) acetic acid (pK₂ of 4.76) formic acid (PK, of 3.8) pH 5 Answer Bank boric acid (PK, of 9.24) pH 9 hydrazoic acid (PK, of 4.6)
- Why is pH balance in water important?Define the term buffer. Explain the difference between carbonic acid (H2CO3) and hydrochloric acid (HCl). Can they both be used as buffers? Why or why not.Define the terms acidic, basic, acid, and base. Also define pH and describe the relationship between pH and the H+ concentration of a solution.
