Bruno Darbouret. a pH value tells us how much H. +. is in a solution. It can be defined by: pH = - log[H. +. ] (log is to base 10). . . (Also note, square brackets are used to denote concentration values); For example: pH = -log[10. Elements in Group 1 are called . alkali metals. . lithium, sodium, potassium, rubidium, cesium, and francium . • Alkali metals are so named because they are metals that react with water to make alkaline solutions. .

What connects these . The pores can be sealed (closed-cell foam), or they can form an interconnected network (open-cell foam).. The defining characteristic of metal foams is a very high porosity: typically 75-95% of the volume consists of void spaces.. Getter Sources vs. Metallic Evaporation Sources. Charlie Sinclair.
