Which of the following is true for a buffered solution? The solution resists change its [H^+] The solution will not change its pH very even if a concentrated acid is added. The solution will not change its pH very much even if a strong base is added. Any H^+ ions will react with a conjugate base of a weak acid already in solution. All of these

A weak acid is defined as an acid that ["dissociates completely in solution", "does not dissociate at all in solution", "does not burn as much as a strong acid", "dissociates partially, but not completely, in solution"] and has a Ka value that is larger than ["1.00 x 10^(-7)", "1.00 x 10^14", "1.00", "1.00 x 10^(-14)", "7.00", "0.00"] and lower than ["1.00 x 10^(-14)", "1.00", "0.00", "7.00", "1.00 x 10^(-7)"] .

please help l, will rate! thabk you!!
Why does a solution of a weak acid and its conjugate base act as a better buffer than does a solution of the weak acid alone? The presence of both the acid and the base provides a significant concentration of both an acid and a base, making it harder to change the pH A solution of a weak acid alone has no base present to absorb added acid. The presence of both the...
