What is DCPIP?
The fullform of DCPIP is 2,6- dichlorophenolindophenol.
Are chloroplast necessary for reduction of DCPIP and why?
Chloroplasts release electrons when stimulated by light the DCPIP accepts the electrons and becomes colourless
What effect does crushing the tablet have on solution?
You get the solution faster than uncrushed tablet. At times a patient can not swallow the tablet and crush it before swallowing. But it is is not recommended to crush the tablets. That is problematic in case of delayed or sustained release tablets as well as for enteric coated tablets. You have the disturbed phrmacokinetics or the drug may get destroyed by acid in the stomach.
Calcium tablets to be chewed?
You can chew some calcium tablets. When buying the tablets make sure it says chew-able.
What do you add to solvent to make a solution?
To make a solution you add a solute to a solvent.
How do you prepare DCPIP solution?
1 % DCPIP solution can be prepared by dissolving 1g of the dye in 100cm3 of water
What is the mass of DCPIP powder needed to form 300 mL of 1percent DCPIP solution and all measurements in grams and millilitres?
3 g
How does dcpip in the hill reaction affect absorbance?
DCPIP is a blue colour when its oxidized and when it is reduced it turns into a colourless solution. DCPIP replaces NADPH the final electron acceptor in the light dependent reaction. So basically, as the reaction continues, the more DCPIP is reduced and the absorbance decreases.
How do you determine the concentration of ascorbic acid in unknown sample?
first measure the volume of the sample solution needed to change the blue color of the DCPIP solution into colourless. then, weigh the mass of the sample solution. finally calculate the concentration by using the formula: volume required t change the color of DCPIP solution (dm) per mass of the sample solution (g)
What is DCPIP?
The fullform of DCPIP is 2,6- dichlorophenolindophenol.
How many 60 mg kmno4 tablets are needed to make following solution kmno4 1 5000 600 ml?
2 TABLETS
Why did we have to make a solution from the tablets?
It helps d clubs to no d position they are,and to move foward?
Which form of DCPIP reduced or oxidized is higher in energy?
DCPIP oxidized is higher in energy
What are the risks of DCPIP?
hmmm.. Safety gloves should be worn in case of a spillage of DCPIP but it's optional. Spilling DCPIP may cause staining on the skin or the surface you are working at. Risks of DCPIP Are extremely low. Do not consume the DCPIP or purposely inhale the substance in case of any dangers or problems related with doing so.
Is dcpip harmful?
no its not
Are chloroplast necessary for reduction of DCPIP and why?
Chloroplasts release electrons when stimulated by light the DCPIP accepts the electrons and becomes colourless
How could determine the concentration of ascorbic acid in an unknown sample?
The concentration of ascorbic acid in an unknown sample can be obtain by conducting a few steps by using the DCPIP test. Firstly, we must obtain the volume (dm ) of the sample solution which are required to turn the DCPIP solution (blue) colour into colourless. After obtaining the volume we use an electronic balance to obtain the mass of the sample solution in gram (g). Then we use the concentration formula of [mass (g) of solute per volume (dm ) of solution] to find out the concentration. Hence. The concentration obtained was the concentration of ascorbic acid.
