All calibration procedures assume that the labeled values of the calibration buffers are correct. But buffer values can change over time and so can your results. A ...
A dot and cross diagram for sodium chloride suggests that it is made up of pairs of sodium and chloride ions. It is not. A 3D construction model shows how the ions are arranged in a lattice structure.
