H2CO3 is not used as buffer.
NaHCO3
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.
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.
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.
No, sand and water mixed together don't make a solution

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?

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.

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.
