Question 5 options: conjugate acid; conjugate base conjugate base; conjugate acid proton donor; proton acceptor proton acceptor; proton donor B and D

The Henderson-Hasselbalch equation can be used to calculate Question 4 options: the pKa of a weak acid. the amount of salt and acid to add to form a specific buffer. the pH of a solution of an organic acid. All of the above A and C only

Calculate to 2 decimal places, the ratio of base/acid at pH 12. Show all details of your working out. In each step of your working out use the chemical formulas of the compounds that constitute the weak acid and conjugate base. State the final answer in a complete sentence.

A strong acid:Group of answer choiceshas a higher pH than a weak acid of the same concentrationrequires fewer moles to neutralize a strong base than a weak acid doeshas a stronger conjugate base than a weak acidproduces a higher concentration of its conjugate base than a weak acid does
