What is the ratio of equivalent weight of kmno4 in acidic and basic and neutral medium?
The ratio of equivalent weight of KMnO4 in acidic to basic medium is 1:2:5. In acidic medium, KMnO4 reacts as MnO4^- + 8H+ + 5e^- → Mn^2+ + 4H2O, requiring 5 equivalents, whereas in basic medium, it reacts as MnO4^- + 2H2O + 3e^- → MnO2 + 4OH^-, requiring 2 equivalents. In neutral medium, the equivalent weight is the same as in basic medium.
Why do you do a precipitation titration in a basic medium?
Precipitation titrations are often performed in a basic medium to ensure that the precipitate formed is insoluble and does not redissolve. The basic medium helps to keep the hydroxide ions from interfering with the precipitation reaction, allowing for more accurate and reliable results.
Why phenolphthalein get colour on basic medium?
Phenolphthalein is colorless in acidic solutions but turns pink or purple in basic solutions because the hydroxide ions in the basic medium react with phenolphthalein to form a pink-colored compound. This color change is due to a shift in the chemical structure of phenolphthalein when exposed to a basic environment.
What are the basic component of data communications?

What is the basic components for a basic laser?
The basic components of a laser include an energy source to pump the laser medium, a laser medium that amplifies light, and optical components like mirrors to create feedback and produce a coherent beam of light. Additionally, a laser typically has a mechanism to control the output such as a cavity to contain the medium and shape the beam.

What is simple medium and complex medium?
Simple medium contains a basic nutrient source for the growth of microorganisms, while complex medium contains more complex ingredients such as extracts from plants or animals. Complex medium usually provides a wider range of nutrients to support the growth of diverse microorganisms compared to simple medium.
