(Redirected from Diphacinone). 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 Indicators: The most common method to get an idea about the pH of solution is to use an acid base indicator. An indicator is a large organic molecule that works somewhat like a  color dye. Whereas most dyes do not change color with the amount of acid or base present, there are many molecules, known as acid - base indicators , which do respond to a change in the hydrogen ion concentration. Most of the indicators are themselves weak acids. The most common indicator is found on litmus paper.
