Indicators are special dyes that "indicate" the presence of a specific chemical by turning color. When the Bromothymol Blue (BTB) has a neutral pH, the solution will be slightly green. When the BTB has a slightly acidic pH, the solution will appear yellow. When the solution is slightly basic (alkaline), the BTB solution will appear blue. 脳

at the end point, between pH 8.0 and 9.6, the solution appears to be green (an equimolar mixture of yellow and blue) Since the equivalence point for the titration (pH=8.7) occurs within the pH range for the visible colour change of the indicator (the end point between pH 8.0 and 9.6), this indicator can be used for this titration.
