WebThe molarity of the NaOH solution would have been half what you expected. Suppose that the NaOH sitting on the shelf had absorbed 2 g of water for every 1 g of NaOH. How would this have affected your results? The molarity of the NaOH solution would have been one third what you expected. In chemistry, a half reaction (or half-cell reaction) is either the oxidation or reduction reaction component of a redox reaction. A half reaction is obtained by considering the change in oxidation states of individual substances involved in the redox reaction. Often, the concept of half reactions is used to describe what occurs in an electrochemical cell, such as a Galvanic cell battery. Half reactions can be written to describe both the metal undergoing oxidation (known as the anode) a… WebFeb 25, 2024 · Explanation: Mass and charge are conserved in all chemical reactions, and for redox reactions this conservation of charge is quite explicit. Redox reactions invoke electrons as virtual particles that are LOST upon oxidation, and are gained upon reduction. See this old answer for a few examples. sharon sheeley death
