F11 8 138 ANAL0464: Comparing the Resistance of Buffered and Unbaffered Solutions to pH Change 3. a) write the chemical equation for the reaction that occurs when you add NaOtH solution to a CH3CO H/NaCH CO, buffer solution. 2) Write the chemical equation for the reaction that occurs when you add HCI solution to a CH CO H/NaCH3CO2 buffer solution. or each of the following solutions, state what the solution color would be. Use Table 1 for the pH/ olor correlation of the Universal Indicator and the information following Table 1 for the pH/color rrelation of Orange IV indicator. A pH 9 solution containing Universal Indicator. Tne universal indicator color for a p ois bueExplanation / Answer
(1)
When NaOH is added to acetate buffer, the following reaction occurs:
CH3COOH + NaOH ---> CH3COONa + H2O
Thus the amount of salt increases and the amount of acid decreases.
(2)
When HCl is added to acetate buffer, the following reaction occurs:
CH3COONa + HCl ---> CH3COOH + Na+(aq) + Cl-(aq)
Thus the amount of acid increases and the amount of salt decreases.
Hope this helps !
