Hello, i'm here to ask about this, drawing the graph.
I have searched lots of articles which show the graphs similar with attached image. However those articles does not have any information about how to draw it.
As far as i know, before i draw it, i need the reactions occurred. For example, Sn(2+)+OH(-)=Sn(OH)(+), with solubility product constant(Ksp) or ionization constant.
But i don't make any progress after this. What am i supposed to do?
Please give me a help.
This is described in numerous textbooks. You may try this software, which is free to download

Dear Sir. Concerning your issue about how to draw graph of ion concentration versus pH . I think the following below links may help you in your analysis:

Thanks
Mr. Namgung,
These are a number of discrete points, which is fitted off using a nonlinear function. Thus, you have obtained the final picture.
You can find possibly useful discussed calculations on the solubility of metal hydroxides in water at some classic analytical chemistry textbooks; e.g.: D.A. Skoog, D.M. West, “Fundamentals of Analytical Chemistry”, 3rd ed., Holt-Saunders Int. Eds., 1976, pp. 99-101; or later eds. (e.g. 8th ed., also co-authored by: F.J. Holler, S.R. Crouch, Thomson Press; 2003; Ch. 15); or last ed. (9th), Cengage, 2014: https://www.cengage.co.uk/books/9780495558286/
