Calculate the p H of a buffer solution made from mixing 75 mL of 0.14 M H A and 59 mL of 0.10 M N a A. The K a for H A is 5.8E-6.

Expert Solution

Step 1

A buffer is a solution that, upon the addition of an acidic or basic part, can resist pH changes. It is capable of neutralizing small quantities of additional acid or base and thereby keeping the solution 's pH relatively stable. For processes which require complex and stable pH ranges, this is essential. Buffer systems have an operating pH set and capability that determines how much acid / base are being neutralized and the extent by which it can change before pH changes.
