Indicators change colors over about 1-15 ph units for

Question- Part 1) If 10 mL of a 0.20M CH3COONa and 10 mL of 0.10M CH3COOH (Ka=1.7 x 10^-5) are mixed, using a one step solution, state the value of the pH.

Part 2) Indicators change colors over about 1-1.5 pH units. For bromthymol blue, the pKa is about 7.0. Estimate the pH range over which the color change occurs for bromcresol green indicator.
