The catalyst indicators is a voice assistant which helps in finding the color change of indicators in acidic and basic medium. The conversation starts after saying the wake words "Talk to Catalyst indicators". Once started the commands can be given, without using the trigger phrase again. In order to reply Catalyst accepts both voice and text entry. The user can mention the indicator for which the information is required by saying the compounds common name, IUPAC name or its chemical formula. For example, on giving the command "phenolphthalein " or "C₂₀H₁₄O₄" the color change of indicator is provided. One can continue the assistance by mentioning another indicator. The role of indicator in titration is to detect the endpoint of the titration. When the color of the solution changes, it indicates that the concentration of the chemical specie has reached a critical range. This change in color is possible with the help of indicators.. Hope catalyst equivalent weights can guide you by giving the necessary information. "EXPLORE CHEMISTRY BEYOND"
