Permeable Porous material, to allow solution flow, yet small enough in size, to catch particulate material.
pH pH is a measure of the acidity or basicity of a solution. It is defined as the cologarithm of the activity of dissolved hydrogen ions (H+). Pure water is said to be neutral, as the pH at 25C is close to 7.0. Solutions with a pH less than 7 are said to be acidic, and solutions with a pH greater than 7, are said to be basic or alkaline. Note: In chemistry, a decimal cologarithm is indicated by the letter p. For example, pH = -log10 {H+}. » More Electroplating Terms |
