CHAPTER 19 – CHEMICAL HANDLING AND STORAGE
www.sifacilities.si.edu7. If acids and bases must be stored together in the same cabinet, place each in separate secondary containers (non-reactive trays) on opposite sides of the cabinet to minimize intermingling in case of a spill or drip (in other words, do not store all the acids on one shelf, and all the bases on the shelf below).

www.bu.eduKw =1.μ10-14 =x2 and so the concentration of H3O + and OH-are each 1μ10-7 M at 25°C. Now, as we will see in a moment, strong acids can have H3O+ concentrations of 1 M or more. This means that H3O + varies over many powers of 10 (orders of magnitude), and so it is convenient to measure [H3O +] on a logarithmic scale. Also, for weak acids and ...
