WebNov 17, 2024 · Alkalinity measurements are based on titration of a water sample to a designated pH using diluted sulfuric acid (0.1N or 0.02N H 2 SO 4) as a titrant and a pH meter for measuring the pH (Figure 1). One mL of 0.1 N H 2 SO 4 is equivalent to 5 mg of CaCO 3 , and 1 mL of 0.02 N H 2 SO 4 is equivalent to 1.00 mg CaCO 3 .

WebJul 26, 2024 · pH The pH of a pond or lake should generally fall between 6.0 and 9.0. Different types of fish tolerate different pH levels but, in general, most fish will do better in ponds with a pH near 7.0. Ponds with a pH less than 6.0 may result in stunted, reduced or even absent fish populations. Low-pH ponds are often treated by applying limestone. WebNov 17, 2024 · What Is Surface Water?
