H2CO3 is not used as buffer.
H2CO3, also known as carbonic acid, can be produced by combining CO2 (carbon dioxide) and H2O (water). To make sodium hydrogen carbonate (NaHCO3), you can react sodium (Na) with carbonic acid (H2CO3), resulting in the formation of NaHCO3.

For the preparation of a solution with the pH=7,00:Add 29,1 mL sodium hydroxide solution 0,1 M to 50 mL potassium dihydrogen phosphate solution 0,1 M.
Bicarbonate can react with hydrogen ions to form carbonic acid, which combines with water to produce carbon dioxide and more water. The carbon dioxide is expired through the lungs thus helping maintain pH equilibrium in the body.
1. stain with leishman stain for 3 minutes 2. poured with buffer solution for 10 - 15 minutes, make sure the blood film is flooded with the buffer solution. 3. rinse with distilled water to clean the remaining stain. 4. air dry. this is the most simple step and easy to remember! good luck!

Make Solution A by dissolving 174.18g of K2HPO4 in 1L of dH2O. Make solution B by dissolving 136g of KH2PO4 in 1L of dH2O. now mix solution A and B and finally adjust pH of your buffer.
I don't know how to make the solution below. Low salt buffer: 10 mM phosphate buffer, 10 mM NaCl, pH 7.4. Could you tell me the method in detail?
A buffer is used to resist the change in pH when acid or alkali is added to a solution. This makes it a stable environment, eg. for enzymes. The buffer stops the pH of the solution changing too drastically.
can I make sodium acetate buffer 0.2M Ph=5 whit sodium acetate buffer 3m Ph=5 solution?
Vinegar (acetic acid) is a weak acid, so yes it can be used to make a buffer.
You can create a ph 9 buffer solution by mixing together a slightly stronger acid and a base, as the acid will override the bases basic functions and great an acidic solution.
you can prepare 20nM sodium phosphate buffer pH7.0. calculate mass of enzyme and dilute in volume buffer to reach concentration you want. good luck
to make 500ml of 1x TAE solution we have to take 5ml of 100x TAE solution. mix it in 495 ml of deionized water.
A buffer is supposed to keep the pH of a solution from fluctuating too much. It helps keep the pH more-or-less consistent. Whether it keeps the solution neutral, it doesn't have to be neutral. You can make a solution be whatever pH you want, but different solutions and pHs require different approaches.
When mixed, it is a solution. If left to sit, the salt can partially distill out of the solution. If the water is left to evaporate, there will be crystals.
