(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.
1 When we want to decide whether a solution (in water) is acidic or basic, we can measure its pH. 2  One of the ways pH can be measured, is with an acid-base indicator, such as universal indicator. 3  An acid-base indicator is a substance that changes its colour depending on the pH of the solution that it is added to.e know that some substances change colour when they react with an acid or a base. These substances are called acid-base indicators, which can show us if a substance is an acid or a base. Different indicators change colour at different pH values.
