WebApr 13, 2024 · PH buffers are special solutions which prevent large variations in pH levels. Every pH level produced has a specified buffer capacity and buffer range. The capacity of the buffer refers to the amount of acid or base which can be added before the pH alters substantially. It may also be characterized as the level of strong acid or base that needs ... Web10 mM Tris-Cl, pH 8.5; Buffer EB is the elution buffer used in the QIAquick PCR, Gel Extraction, Nucleotide Removal Kits, and MinElute Kits for DNA cleanup, and the QIAprep Miniprep Kits for small-scale plasmid purification.

So let's compare that to the pH we got in the previous problem. For the buffer solution just starting out it was 9.33. So we added a base and the pH went up a little bit, but a very, very small amount. So this shows you mathematically how a buffer solution resists drastic changes in the pH.
