when the colour persists/ stays for a longer period of time before going colourless again
Molecular weights from titration are typically found by titrating a solution of known concentration with a reagent of known concentration. By measuring the volume of titrant required to reach an endpoint, one can determine the moles of titrant reacted. By using the stoichiometry of the chemical reaction, one can then calculate the molecular weight of the compound being titrated.
An indicator is used to determine the pH of a solution by changing color at specific pH levels. It provides a visual signal of whether the solution is acidic, neutral, or basic based on the color change it undergoes. Indicators are often added to solutions during titration experiments to help determine the endpoint of a reaction.
You can tell which family member is approaching you by recognizing their unique physical features, gait, voice, or mannerisms. These distinct characteristics can help you identify who it is without needing to rely on facial recognition.
Swirling the flask during a titration is important to ensure thorough mixing of the reactants, leading to a more uniform reaction. This helps in achieving accurate and consistent results by promoting a faster and more complete reaction. Additionally, swirling the flask helps to prevent localized concentration variations, ensuring that the endpoint of the titration is accurately determined.
I don't know ... I have the same problem . I found this in a chemestry problem , and my teacher couldn't tell me the answer . He told me to search for it, but I can't find anything about the reaction between Methyl Orange and HCl .. If you could help me , please leave a message at YM : valentin_gr2008@yahoo.com Thanks !
Phenolphthalein is chosen as a suitable indicator for sodium hydroxide because its color change occurs in the pH range around 8.2 to 10.0, which is close to the pH range of the equivalence point for the titration of a strong base like sodium hydroxide with a strong acid. This allows for a sharp and easily detectable color change at the endpoint of the titration.

Ok, that's a form of approaching. Now, depends of your reaction to that. Obviously, he's interested on you, but the kind of interest, only you can tell afterwards.
