  1. I am amazed by your curiosity! As for the electrolysis of NaCl solution, you can't go much wrong, given that you know what you are doing. I would say that for every experiment you may do by varying the electrodes, you should research about the reaction from sources online that you would find easily. As for the electrolysis of the NaCl solution with graphite electrodes, you get Cl2 gas at anode (+), H2 gas at cathode (-) and NaOH in the solution. As the reaction proceeds and if both electrodes are not far enough, the Cl2 gas reacts with the NaOH in the solution to form Sodium hypochlorite or bleach. Only risk in here is the chlorine gas that you should not inhale too much. So don't smell it for too long. Also, the reaction with copper electrodes is also safe. I have a youtube video on the same on my channel Curiosity Catalase ( ). May be you find it helpful! I would love to answer anymore questions you would have. Have a fun and safe experimenting! Good luck!

  3. I need suggestions over differentiating between a solution of sodium hypochlorite (let's say the household bleach) and sodium chlorate solution. Is there a qualitative way to test and differentiate the two, considering that if I make chlorate from hypochlorite, I want to confirm the reaction..? Thanks in advance!
  4. have you thought of quantifying the vitamin c through DCPIP titration or what? Also, other vegetables could be bell peppers that have a lot of vitamin c.

    That's a weird idea! How would those oxygen synthesizing bacteria/ phytoplanktons survive if all the trees disappear? There is something called interdependency in biosphere, that makes healthy ecological communities. Also there are other climatic influences of trees that is part of our survival
  6. You want a satisfactory theory of life? Why not analyze life through the perspective of biology, then chemistry and then physics. We will ultimately reach the level of energy, the quantum world! I know the hard part lies in explaining why all this orchestrates to form living matter, but if you build up from scratch you will realize that all the cells, organization in body, processes, senses, emotions, intellect is just the energy in the atoms expressing its information in different creative ways.
  7. Are you sure you've named the substrate correctly?
  8. Look into the bonds of the chemicals involved. The extra energy is from the unstable bond oh h nd cl which keeps the two bonded but immediately gets released as heat energy from bond dissociation.
  9. No they are grapes from the same bunch
  10. Green Grapes that are ripe and soft seem to taste more sour( tarter), while the stiff ones are much sweeter. How is it unlike other fruits grapes become tarter with ripening? Or is it to do just with enhanced tartaric acid and not actually the sourness?
  11. Traces of arsenic, lead, nickel, cadmium I suppose as heavy metals. Then some vital ions like fe3+, cl-, ca2+,etc, can be present in natural water. But how are you going to detrct such trace quantities?
  12. Can diamagnetic materials like superconductors act as shields against magnetic field?
  13. Theoritically we have read that ketones do not get directly oxidized by potassium permanganate aqueous solution. However, when I tried doing so with acetone, the pink color did diffuse to red, then orange and then yellow;but very gradually. This means acetone was oxidized by kmno4! How should I account for this?
  14. I need itfor some colorimetric calculations... And what about kmno4 at 600nm
  15. I need the molar absorption coefficient for sodium chloride at 600 nm... Any help?

    So isnt their an equation that will include resistance and intensity in proportion and other factors of the ldr in a constant?
  17. smhjn17


    Is their an equation for an LDR that can convert the value of resistance obtained into the incident light intensity?
  18. The skeleton of spider's silk is protein, right ?... But on testing a water sol. Of it with ninhydrin and biuret reagent no reaction is observed! How could this happen?
  19. When i left the milk to spoil for a day, there was a floating protein mass and a sedimented protein mass ....can i get the explanation why some protein coagulum floats on the surface? Is it because of the gases produced by the bacteria that it moved to the top???
  20. I added benedict reagent to the albedo extract from the peel of a citrus fruit and what happened ?.. The solution just turned green without any heating ...what can be the cause ???
  21. Thnx...but how come reptiles have appeared earlier than frogs n salamanders
