WebBecause this equation has two unknowns—g KCl and g NaBr—we need another equation that includes both unknowns. A simple equation takes advantage of the fact that the sample contains only KCl and NaBr; thus, g NaBr g g KCl = − 0 3172. g KCl 74.551 g KCl/mol KCl g g KCl 102 + − 0 3172..89 g NaBr/mol NaBr = × − 4 048 10 3. 1 341 10 3 083 ...

WebAug 30, 2024 · The answer is 1.2 L of 3.4 M HI required to reach the equivalence point with 2.1 L of 2.0 M KOH. Alternatively, as the required mole ratio of HI to KOH is 1:1, we can use the equation M1V1 = M2V2 to solve the problem: (3.4 M) (V 1) = (2.1 L) (2.0 M) V 1 = (2.1 L) (2.0 M) / (3.4 M) = 1.2 Problems Involving pH WebExplain why increasing extracellular K reduces the net diffusion of K out of the neuron through the K leak channels. Your answer: 1. The concentration gradient is reduced 2. Less K+ diffuses out of the neuron. Explain why increasing extracellular K causes the membrane potential to change to a less negative value.
