This caused the value, of the number of moles of HCl needed to neutralize NaOH, to be more accurate. For calcium, the gas produced in a test tube by the downward displacement ... ... conversion of hydrogen peroxide (H2O2) into water and oxygen gas. 2. Curcumin is yellow in acidic and dark yellow in basic solution, but if strong base, it become dark brown.And, because the pH range of curcumic is >7 (more than 7), it’ll base indicator, and it can used as indicator of titration, and with it, we can determine the equivalent point when the end point finally reached. Titration is a very useful laboratory technique in which one solution is used to analyse another solution. When the color changes to the specified color, the titration has reached endpoint.
