Finding pH of a solution is a well established field of chemistry. I feel you could have done it easily by searching in google. or visiting your nearest chemistry Lab. Surprised by the question
i want to clarify something; i know that PH can be measured using PH meter or even PH paper
my question was
how much i need to take acidic PH (1 or 2 or 3 or 4 too acidic or 5 or 6 slightly acidic ) and how much neutral 7 or 7.1 or 7.4? and when basic will it be 14 PH or 10 or even 8 is good ?
that's my question researchers
i surprise from many answers, really!
this site is for sharing the knowledge and i am new the field and i always try me best to answer my questions with google other asking it here!
In nanoparticles synthesis, if I understood your question correctly...you can adjust the pH by the addition of any of HNO3,HCL,H2SO4 or NH4OH, NaOH. Monitor with a pH meter.
@ Sondos 1 mM is a concentration.... How much you add will depend or are you considering this as the background?
A basic knowledge will tell you that 1 M HCl has a pH of 0 and thus millimolar (0.001M) HCl will have a pH of 3. Similarly millimolar NaOH will have a pH of 11. If you need to control the pH for the reaction you are better off with a buffer. I assume you're doing something like producing silver nanoparticles with a 'green synthesis'. Here the normal precursor would be the diammine silver complex which is alkaline. Monitoring with a pH meter is the easy part.
