Preparations of solutions: 1. 1000 cm3 of 0.0020 M NaBH4(aq): Weigh 0.076 g of NaBH4(s) and dissolve it in deionised water to volume in a 1000 cm3 volumetric flask. 2. 1000 cm3 0.0010 M AgNO3(aq): Weigh 0.17 g of AgNO3(s) and dissolve it in deionised water to volume in a 1000 cm3 volumetric flask. 3. 200 cm3 of saturated NaCl(aq): Add excess amounts of NaCl(s) into 200 cm3 of deionised water. Note: the sodium borohydride solution must be freshly prepared before the experiment session starts.
its a great job
references please??
How to separate the silver nano particles from silver nano solution?
After centrifugation for 5 min and then put it in oven at 70 degree
How to calculate the drug loading in silver nanoparticles?
What's the concentration of the result silver nanoparticles
its written on the bottle.. watch again..
what is the percentage of Nacl solution and what is the final percentage of Silver nano and also the size of silver sir
What happened when you add NaCl solutn to silver nanoparticles??
the ionic strength of the solution rose and thus resulted in an aggregation of the nanoparticles
@@valerylegasov278 thank you..
Good morning
Could you please send me theis research paper Link... Thank you
What stabilizing agent you r using ?
NaBH4
@@amritkumar2381 Does sodium borohydride stabilize as well as reduce?
None, I think.
I would use one drop of 0.3% Polyvinylpyrollidone solution + 1 drop of 0.3% sodium dodecyl sulfate as stabilizers...
How can I get silver nanoparticle in a larger quantity using this method
I followed your method but after adding the silver nitrate in sodium borohydried i got black color in the solution
Maybe your solutions were not dilute enough?
Also possible is that their NaBH4 decomposed so much that only a tiny bit of Ag was reduced.
why we keep the speed 1 drop per second? reason for it and also why we immediately stopped stirring when the solution has been poured completely?
As we are changing it to Make it basic..so it can immediately be basic after adding of base
As it is titration process
please give a reference paper
Hello, I dont known how to prepare NaBH4 solution. Can some one tell me pls
Preparations of solutions:
1. 1000 cm3 of 0.0020 M NaBH4(aq): Weigh 0.076 g of NaBH4(s) and dissolve it in deionised water to volume in a 1000 cm3 volumetric flask.
2. 1000 cm3 0.0010 M AgNO3(aq): Weigh 0.17 g of AgNO3(s) and dissolve it in deionised water to volume in a 1000 cm3 volumetric flask.
3. 200 cm3 of saturated NaCl(aq): Add excess amounts of NaCl(s) into 200 cm3 of deionised water.

Anyone can guide me how to prepare a nanoparticle of silver nitrate???
