The test samples of anesthetic drugs were prepared by diluting 100–500 μL of each injectable solution up to 100.0 mL with 0.1 M acetate buffer solution (pH 4.67). For the analysis of urine, enzyme-free samples (10 mL) were spiked with the calculated amounts of an anesthetic salt and left stirred for 5–10 min.

How does temperature affect pH? - TRUEscience

Jan 19, 2017 · However this is different for every sample, so it is difficult to compensate for it. For example, a sample tested at 25°C may show a reading of pH 14.00, but when the exact same sample is heated to 60°C it could change by as much as 1 pH unit. The effect is generally greater in alkaline or basic solutions than in acidic solutions.

Ways to measure pH

Ways to measure pH

To find the specific pH of a sample, you will need a pH test paper or strip that is more precise than a litmus strip. More precise pH test papers or strips can give test results down to 0.2 pH units. There is a large selection of pH test papers and strips available, from wide pH range, low sensitivity to narrow pH range, high sensitivity.
