Dear colleagues
pH setting such as for testing the stability of photocatalyst (or other materials) is one of the important thing. Generally, this condition can be adjusted by pouring or dropping some acid or base compound droplets like HNO3 (nitrate acid), HCl (chloride acid), NaOH (sodium hydoxide) and so on. But, I think there're some main considerations to choose one of them. Maybe, there some of you can share tips to select a proper acid and base compounds in controling pH situation especially in inorganic synthesis material, pH stability, or dye photodegradation?
Thank you very much.
I'm really surprised to see this question. There is nothing to discuss. Just open a general chemistry textbook and read about buffers.
Dear Yurii V Geletii
Thank you very much for your answer, Sir. But, I think there are some of reactions that is not covered by a general chemistry textbook especially for specific reaction. Ex: a complex reaction in the dye photodegradation using photocatalyst based materials. It can be started via radicals generation. Suprisingly, pH is one of the important thing here. So, maybe there are tips to make this reaction better.
Your question was how to keep pH constant. I answered you. Use a buffered solution. Nothing to discuss.
