(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: A graphic view. A pH indicator is a halochromic chemical compound added in small amounts to a solution so the pH (acidity or basicity) of the solution can be determined visually. Hence, a pH indicator is a chemical detector for hydronium ions (H 3 O +) or hydrogen ions (H +) in the Arrhenius model.cid-base-indicators: A graphic view.
