WebIn this colorimetric method, use for drinking water, wastewater and seawater, nitrate is reduced to nitrite with hydrazine sulfate. The diazonium reagents then react with the nitrite to produce a red color. The intensity of the color is proportional to the original amount of nitrate and nitrite present in the sample. WebAcids are substances that dissociate into H+ ions when you dissolve them in water. They have a higher concentration of H+ ions than OH- ions and in the pH scale, they range between 1 or more than 1 but lesser than 7. They turn blue litmus red. Bases are usually oxides or hydroxides. They dissociate into OH- ions when you dissolve them in water. WebMar 16, 2024 · Here are the steps to calculate the pH of a solution: Let's assume that the concentration of hydrogen ions is equal to 0.0001 mol/L.
