    Can you make a video on how to compare our results with a standard?

      Thanks for your suggestion. I have note down your suggestion

    can we use this equation to calculate conc. if unknown sample absorbance value higher than ploted values?

    how do we know that the calibrated graphic that we made is correct sir?

    • @TeachingJunction

      There are multiple factors. Firstly, make sure that your values falls into a linear range. Secondly, the value of correlation coefficient and coefficient of determination is also indicate the accuracy of calibration curve

    How did you find the value of concentration, as well as absorbance? please let me know
    Thank you

      You can get these values from experiment. I have used imaginary values for demonstration purpose

    Why u use 0.0249x like where did u get the value?

    • @TeachingJunction
      @TeachingJunction  2 ปีที่แล้ว +1

      That is the intercept value. you can get this value from regression equation generated by excel

      according to equation we have to use both slope and intercept. but you are using only one why?

    Please find the unknown concentration without the trend line equation. It's highly advicable not use the equation in most experimental reports

      Do you mind sharing how to go about doing that?

      TREND(select the concentration of std.,select the O.D of std.,select the O.D of unknown sample)
      Do this in excel

    Don't use English title for your video if you are not making an english video. It is very cheep when you do a video in your own language and use a title from another languages.

      Actually, you are a cheap person. Think before you speak. I am using English language as teaching medium. The people from more than 50 countries are taking advantage from these video. You have a sick mentality
