The normality of the hydrochloric acid when 19.30 mL of it is titrated with 2.00 g of Na 2 CO 3 in water is to be stated. Concept introduction: Normality is defined as the number of equivalents of solute per unit volume of the solution. Equivalent mass is the mass of the compound per equivalent. One equivalent of any substance means it would react with or supply 1 mole of electron or protons in a reaction. The normality of a solution is a measure of concentration. It is equal to the ratio of gram equivalent weight to the volume of solution in liter. General expression is shown below. Normality = Gram equivalent of solute Volume of solution in liter

Imagine separating this process into the four stages sketched below. (These sketches show only a portion of the substances, so you can see the density and distribution of atoms and molecules in them.) CH,CN H₂O B 88 C Use these sketches to answer the questions in the table below. The enthalpy of solution AH is negative soln when CH3CN dissolves in water. Use this information to list the stages in order of increasing enthalpy. Would heat be absorbed or released if the system moved from Stage C to D? What force would oppose or favor the system moving from Stage C to D? Check all that apply. 1 absorbed O released neither absorbed nor released. none O ionic bonding force covalent bonding force…

In a system with an anodic overpotential, the variation of ŋ as a function of the current density: 1. at low fields is linear 2. at higher fields, it follows Tafel's law Find the range of current densities for which the overpotential has the same value as when calculated for cases 1 and 2 (maximum relative difference of 5% with respect to the behavior for higher fields). To which overpotential range does this correspond? Data: 10 = 1.5 mA cm², T = 300°C, ẞ = 0.64, R = 8.314 J K 1 mol‍¹ and F = 96485 C mol-1.
