WebPOTASSIUM HYDROXIDE, SOLUTION is a strong base dissolved in water. Reacts exothermically with all acids. Slowly dissolves glass. Attacks aluminum and zinc to generate flammable hydrogen gas. Ignited a polyethylene container liner when mixed with potassium persulfate by release of heat and oxygen [MCA Case History 1155. 1955]. WebTranscribed Image Text: When 0.928 g of potassium hydroxide (KOH) is dissolved in 105 g of water in a styrofoam calorimeter of negligible heat capacity, the temperature increases from 25.00 to 27.28 °C. Based on this observation, calculate q for the water and AH° for the process, assuming that the heat absorbed by the salt is negligible.
