浓度极化(Concentration Polarization)是电化学过程中因电极表面反应物或产物浓度与溶液本体浓度差异引起的极化现象。其产生的条件包括:较大电流密度、溶液扩散速率不足、未充分搅拌、低电解质浓度、温度过低。 1. **概念理解**:浓度极化指电极表面附近的离子浓度与溶液本体不同(如阴极反应导致表面反应物耗尽或产物堆积)...

How to calculate the molarity of a solution What is the concentration of h+ in a 2.5 m HCL solution? What is the weight per volume method to calculate concentration? If the pOH of a solution is 9.1, what is the concentration of OH- ions in that solution?
a 15 percent w/v sugar solution has a unit of weight in the numerator, but a unit of volume in the denominator. It is defined as a percentage, somewhat artificially; a 1 percent solution contains 1 gram per 100 milliliters (ml) of solution. This form of percent concentration is used ...
The concentration of a substance can be measured in several ways. It may be grams over liters (gram concentration), moles over liters (molar concentration), or mililiters per 100 mililiters (volume concentration). The way concentration is measured depends on how convenient it is for the lab...
