Question

can someone help with steps plz

Sing a Strong Acid to a Butter Review Constants Periodic Table Part A Abesker with 165 mL of an cetic acid buffer with a pH of 5.000 is siting on a benchtop. The total molarity of acid and conjugate base in this buffer is 0.100 mol L-A student adds 500 ml of a 0.450 mol HCl solution to the beaker. How much will the pH change? The pk, of acetic acid is 4.700 Express your answer numerically to two decimal places. Use a minus ( - ) sign it the pH has decreased View Available in earning Goal To understand how bullers se reserves of conjugate acid and orgate base to ameliorate the effects of acid or base addition on рll Abuferis amicure el conjugate acid-base pair. In other words, is a solution that contains a weak sold and its conjugate base ora wa base and its conjugate acid. For example, an acetic wold buffer consists of acetic acid, CH,COOHand its corate be, CH,COO Because one cannot simply be added to a solution the cougate base is added in a safom #g NBCH C01 Buters work because the conjugate acid-base pair work together to neutralize the addition of HOH Thus, for example, on are added to the state buffer described wbove, they will be largely removed from solution by the reaction oll with the core base H(aq) + CH,COO(g)CH,COOH Smartyr added OH ions will be noted by a roton with the conjugate acid OH(aq) +CH,COOH) CH.COO(g) + HOC This buforystem is desorbed by the Henderson Hasselt equation 190 AEG 4.70 Submit Previous Answers * Incorrect; Try Again; 5 attempts remaining Next > Provide Feedback phpk + logicamente lase
