Diphenadione is a vitamin K antagonist which has anticoagulant effects and is used as a rodenticide against rats, mice, voles, ground squirrels and other rodents.This chemical compound is an anti-coagulant with longer activity than warfarin and other synthetic indandione anticoagulants.iphenadione is highly toxic for human skin by all means of contact. Consumption of the drug may cause major blood clotting abnormalities and irregular heartbeats. An online pesticide database gives more information about the safety of diphenadione.
Indicators are substances which show whether the substance tested is basic or acidic. 1  pH indicator, a chemical detector for protons in acid-base titrations. 2  Redox indicator, a chemical detector for redox titrations.
Acid-Base Indicator Definition. An acid-base indicator is either a weak acid or weak base that exhibits a color change as the concentration of hydrogen (H+) or hydroxide (OH-) ions changes in an aqueous solution. Acid-base indicators are most often used in a titration to identify the endpoint of an acid-base reaction.
