Can be mixed in a solution with H2CO3 to make a buffer?
H2CO3 is not used as buffer.
Why dont molecular compounds conduct electricity when dissolves in water?
Molecular compounds are charge neutral. Molecular compounds dissolve in water as individual molecules. For example if 1.0g of C12H22011 (sucrose or table sugar) dissolves in water the solid will become many individual C12H22011 molecules floating in water but will remain charge neutral. Therefore, this solution does not conduct electricity. This is known as a nonelectrolyte solution. On the other hand, when ionic compounds, like NaCl (table salt), are dissolved in solution they break up into individual ions. In this case Na+ and Cl-. These ions with their respective charges make the solution electrically conductive. This is called an electrolyte solution.

How do you make a neutal substance?
The product of the reaction between a strong acid and a strong base is a salt neutral in water solution.
Is a buffer supposed to keep pH of a solution neutral?
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.

How do you make 1m kh2po4 buffer?
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.
How do you make buffer solution pH10?
See the link below.
How do you make this 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?
Why a buffer is used and the effects of a buffer on a solution?
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.
Sodium acetate buffer?
can I make sodium acetate buffer 0.2M Ph=5 whit sodium acetate buffer 3m Ph=5 solution?
Can vinegar be used to make a buffer solution?
Vinegar (acetic acid) is a weak acid, so yes it can be used to make a buffer.
How do you make pH 9 buffer solution?
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.

Does pH7 makes a solution neutral?
Yes it does make it neutral because 7 is in the middle! :D
