Ph surface water
WebWater that has a pH >8.3 is said to have “phenolphthalein alkalinity,” which is alkalinity due primarily to the presence of carbonate or hydroxide ions. Many water samples have little or no phenolphthalein alkalinity, and therefore remain colorless after adding this indicator to the sample water. Step 2: Total Alkalinity WebJun 1, 2002 · The pH is typically highest near the water surface and lowest near the pond bottom. Samples should be analyzed immediately for pH, for pH can change drastically during sample storage. Conclusion.
