    en.wikipedia.org/wiki/Equivalent_weight

    It is necessary to calculate the mass of a solid acid which will react with about 20 cm 3 of this solution (for a titration using a 25 cm 3 burette): suitable solid acids include oxalic acid dihydrate, potassium hydrogen phthalate and potassium hydrogen iodate. The equivalent weights of the three acids 63.04 g, 204.23 g and 389.92 g ...

    This includes Bis(2-ethylhexyl) phthalate (DEHP or DOP), which has long been the most widely used phthalate, with commercial production dating back to the 1930s. [ 16 ] [ 17 ] In the EU, the use of DEHP is restricted under REACH and it can only be used in specific cases if an authorisation has been granted; similar restrictions exist in many ...

  7. Dipotassium phosphate - Wikipedia

    Dipotassium phosphate (K 2 HPO 4) (also dipotassium hydrogen orthophosphate; potassium phosphate dibasic) is the inorganic compound with the formula K 2 HPO 4. (H 2 O) x (x = 0, 3, 6). Together with monopotassium phosphate (KH 2 PO 4. (H 2 O) x), it is often used as a fertilizer, food additive, and buffering agent. [1]
