Is K2S2O8 an empirical formula?
K2S2O8Potassium persulfate / Formula
How do you make K2S2O8 solution?
1 Expert Answer
There are two equivalents per mole. Therefore, to prepare a 0.1N solution, 0.1 equivalents of the reagent should be added to a 1liter volumetric flask, and water added to the 1 liter mark. Actual weight of reagent needed is 19.03 grams (0.1 mole)/2 = 9.5 grams (0.1 equivalent).

Is potassium persulfate soluble in water?
Potassium persulfate is the inorganic compound with the formula K2S2O8. Also known as potassium peroxydisulfate or KPS, it is a white solid that is sparingly soluble in cold water, but dissolves better in warm water.
What happens when potassium persulfate is heated?
Potassium persulfate is an inorganic salt, soluble in water (5.3 g/100 mL, 20 °C) ( 21) that begins to react strongly and release oxygen when the temperature is raised to 100 °C. The reaction is strongly exothermic.
Why is sulfate not called persulfate?
Answer and Explanation: Hydrogen sulfate is not called persulfate because it contains four, not five oxygen molecules. All of the oxyanions found in nature end in the suffix “ate”. If they have an additional oxygen atom, the prefix “per” is added to the word sulfate.
What is APS chemistry?
Ammonium persulfate (APS) is the inorganic compound with the formula (NH4)2S2O8. It is a colourless (white) salt that is highly soluble in water, much more so than the related potassium salt. It is a strong oxidizing agent that is used in polymer chemistry, as an etchant, and as a cleaning and bleaching agent.
What is reaction between K2S2O8 and Ki?
