6) When working with starch indicator is not one of the things to be considered? A. The indicator should be prepared fresh. If kept waiting, a substance called dextrose is released as a result of bacterial breakdown. Since this substance is reducing, it causes excessive consumption of S2O32-. B. Since the presence of substances such as gelatin and alcohol prevents the formation of amylose-I2 adsorption compound, it should not be present in the environment. C. The indicator sensitivity decreases with increasing temperature. Therefore, it should be worked at room temperature. D. Since starch is not soluble in water, the starch solution must be dissolved in alcohol while being prepared.
