Nitric Acid (HNO3) Neutralization. pH Neutralization

2019-11-12 · Nitric Acid HNO 3: With a pKa of zero (or nearly so) HNO 3 is a very strong acid that fully disassociates at all concentrations. At higher concentrations (gt;5%) the outgassing of HNO 3 can be quite significant and good ventilation is required. The pH neutralization of Nitric acid is conventional and any inorganic base such as sodium hydroxide or lime can be used.

Determination of Hardness of Water by EDTA

2  · Procedure for calculation of hardness of water by EDTA titration. Take a sample volume of 20ml (V ml). Dilute 20ml of the sample in Erlenmeyer flask to 40ml by adding 20ml of distilled water. Add 1 mL of ammonia buffer to bring the pH to 10±0.1. Add 1 or 2 drops of the indicator solution. If there is Ca or Mg hardness the solution turns wine red.

2019-6-1 · The experimental apparatus is shown in Fig. 1.NH 4 OH (30%wt) and (NH 4) 2 SO 3 (98%wt) were used as the absorbents in the initial- and main-absorber. H 2 O 2 (30%w/w) was used as the oxidant, and its concentration was diluted by deionized water if needed. NO, SO 2, O 2 and N 2 were provided by the compressed cylinders (North Special Gas Company, China). The two absorbers were

Testing for halide ions - chemguide

2019-1-27 · This test has to be done in solution. If you start from a solid, it must first be dissolved in pure water. The solution is acidified by adding dilute nitric acid. (Remember: silver nitrate + dilute nitric acid.) The nitric acid reacts with, and removes, other ions that might also give a confusing
