What is the meaning of ''the desired pH adjusted using drops of 2 N HCl and 2 N NaOH'' ?as I would like to do the same recipe to adjust my ph of glucose. Any advice is appreciated, Thank you in advance,
Actually, I don't know what is 2 N of these chemicals, are these concentrations, and if so how to calculate the concentration of these values, please?

The N should read M.
Explanation:
M means molarity (concentration). Or more specifically
You could adjust pH using 2M HCl (Hydrochloric acid) or 2M NaOH (Sodium Hydroxide).
If the pH of your glucose solution is too low (i.e. too acidic) you could add drops of 2M NaOH until the desired pH is reached. This is because you are adding a base (
If the pH of your glucose solution is too high (i.e. too basic) then you could add drops of 2M HCl until the desired pH is reached. Here, you are adding acidic ions (
