The filtrate after the removal of the black precipitate was basified with 6M ammonia. This when treated with 3M ammonium carbonate, it gave a white precipitate. This white precipitate was dissolved in 6M acetic acid and basified with ammonia(6M).
Why is the internal-standard method often used in plasma emission spectrometry?
The average pH of precipitation in rural areas is 7.00. Assuming that the pH is controlled by the carbonate system, i.e., no anthropogenic acid gases are present in the atmosphere.
The empirical formula for acetic acid is CH2O. Its molar mass is 60 g/mol. The molecular formula is
