Please how the change from 50mL to 100mL at the final stage. Please clarify

[@anuragchoudhary7944]

You took 25 ml of sample solution of unknown concentration and add 10 ml ziconyl spadns and then diluted it up to 100 ml. Is this dilution will affect the value of original concentration we want to determine or not , because due to dilution Absorbence will change and hence the concentration.

[@muhammedvahisak1481]

sir what wavelength we use for the mesurement ?

[@anuragchoudhary7944]

Please make next video for spectrophotometric measurements for determining fluoride concentration

[@Laboratoryanalysisofwater]

Okay sure

[@hebamk2591]

Can you help me please, I need to know how I can make a Standard solutions from potassium bromate for measuring the absorbance of potassium bromate in bread samples.

Hello Sir,
Thank you for showing the practical.
It's very helpful

[@Laboratoryanalysisofwater]

You are welcome

[@mohinuddinsujon3211]

From the research paper that did this test. Comment on that site. please sir

[@nehasaini8577]

Can we estimate fluoride in blood by SPADNS solution.

We can make calibration standards in any mL of volumetric flask but we have to calculate how much ml of standard fluoride solution to be pipetted
