Question 1 of 16 Determine the mass of solid NaCH,CO0 that must be dissolved in an existing 500.0 mL solution of 0.200 M CH.COOH to form a buffer with a pH equal to 5.00. The value of Ka for CH.COOH is 1.8 x 10-5. NEXT Let x represent the original concentration of CH,COO- in the water. Based on the given values, set up the ICE table in order to determine the unknown. CH,COOH(aq) H:O(I) H,O (aq) CH,COO (aq) Initial (M) Change (M) Equilibrium (M)
