Ph of phosphate
WebJun 24, 2024 · Phosphate buffer is an important buffer that we use in biochemistry laboratories. It is often used to extract and isolate proteins and enzymes that have optimal pH of around 7. That is because the buffering capacity of a phosphate buffer is pH 7.21 ± 1 within which most of the proteins and enzymes are more stable. WebMar 16, 2024 · The pOH is a similar measurement to the pH and correlates to the concentration of hydroxide ions in a solution. The formula for the pOH is: pOH = -log10 ( [OH-]) In specific conditions (aqueous solutions at room temperature), we can define a useful relationship between pH and pOH: pH = 14 - pOH What are some examples of pH?
