Part A: Conjugate Acid-Base Pairs Practice Write the equation for the reaction of each acid and base given to you in the table below. (5 marks) Acid Base Reaction HCH,COO CH,COO- HF F- H.CO. HCO, HNO, NO, НСО, HSO, Part B: pH and pOH pH is a unitless number used to convey the acidity of a substance without having to deal with numbers in scientific notation. You can go between pH and concentration with these equivalent formulae: pH = -log[H,0"] H0] = 10 The pH value tells us about the acidity of a solution: pH = 7 - Deutral pH <7 - acidic pH > 7 - basic POH is just like pH, except it uses the hydroxide ion concentration: pOH = -log(OH) - [OH] -10

#1: Write the equation for the reaction of each acid and base given to you in the table below. Reaction Acid HCH,COO HF H.CO. HNO HCO. Base CH.COO- F- НСО, NO HSO #2: What is the pH when the [H20"] = 0.0235 mols/L? ph=-log(h30) I
