How to prepare mercury ion solution?

Ben Warmus  Follow
1. Use 0.5% HNO3 to make HG (NO3) 2 not hydrolyze?
is
2 the pH of the hg stock solution was adjust to 6.0, to prevent the formation of hgo particles. The mother solution here refers to HG2+ (0.1 m) with 0.5% HNO3.1.3 Around, do you add alkaline adjustment?I don't think so.
There is no need to adjust the pH of the storage liquid, add nitric acid to inhibit hydrolysis

3 What are the purpose of the application of buffer

Although HG (NO3) 2 is easy to dissolve in water, it seems that hydrolysis occurs? What hydrolysis happened? Is it easy to form HGO precipitation?
Mercury ions must be disintegrated in the aquatic solution to disintegrate water into Liushui synthetic mercury. In encountering a lot of water or boiling water, the phrase of the alkali salt semantic \"does not understand?
This sentence is the response of the right mercury ion in the aquatic solution. It is hydrolyzed or precipitated or it is recommended to read the elements of the inorganic chemistry D area
Reference can read the textbooks written by Higher Education Press publishing in Dalian Polytechnic Inorganic Chemical Teaching Office Is the fourth edition
1. Use 0.5% HNO3 to make HG (NO3) 2 not hydrolyze?
Adding dilute nitric acid is to provide weak acidic environments and inhibit mercury ion hydrolysis. When most of the transition metal formulating solutions, it is basically a corresponding weak acidic environment
2 The PH of the Hg Stock Solution was adjust to 6.0. To present the formation of hgo particles. Here the mother liquid refers to HG2+ (0.1 m) with 0.5% HNO3. If so, the mother liquid pH should be around 1.3, is it adjusted? I don't think so.
Without alkali regulation, it will be hydrolyzed after adding alkali to form an environment that forms a traveler ion that has formed a mercury ion. The environment should be an acidic environment
3 What are the purpose of the application of buffer?
It feels that the buffer solution is to provide a stable environment to facilitate detection or the physiological environment that provides analogy as it is upstairs
I do n’t know if it is right. I hope it will be helpful to you. What are the nature of ions or compounds that need to be configured? You can find the corresponding theory from the textbook

It is recommended that students who are asking about the questions now make every step of the basic knowledge and analysis methods they have done, and do not ask others if they have any questions.

3 What is the purpose of using buffer here
It should be imitating a physiological pH environment
