Answer:

HCO₂H

Explanation:

A buffer is defined as the mixture between a weak acid and its conjugate base, or vice versa, in an aqueous solution.

The HCO₂Na (Sodium formate), is the conjugate base of formic acid, HCO₂H, a weak acid of pKa = 3.75.

Thus, to make a buffer using HCO₂Na, the other substance the buffer should contain is <em>HCO₂H</em>

How do you find the # of sigma and pi bonds using a Lewis dot structure

Lubov Fominskaja [6]

Every single bond is a sigma bond.

A double bond contains 1 sigma bond and 1 pi bond.

A triple bond contains 1 sigma bond and 2 pi bonds.

For example, in acetylene, H-C≡C-H, the sigma bond is formed by the head-on overlap of two sp orbitals. The pi bonds are formed by the side-on overlap of 2p orbitals.
