Axit clohydric

1st titration: NaOH + HCl NaCl + H2O. Why HCl do not react with BaCO3? Why the end point is turbid? • ... But if combined with sulfuric acid the solid barium carbonate will be covered in insoluble barium sulfate and the reaction will slow down or stop completely. The AsolH°(BaCl2,cr) from measurements in H₂O and from measurements in aqueous HCl as a function of the concentration of HCI. 5. The AH°(BaCO3,cr) from (1) the ... 2 HCl (aq) + BaCO 3 (s) → H 2O (l) + CO 2 (g) + BaCl 2 (aq) · Names: Barium carbonate source: wikipedia, accessed: 2019-09-27 · source: wikidata, accessed: 2019 ... First, we need to calculate the moles of HCl. The molarity (M) is defined as moles of solute per liter of solution. So, moles of HCl = Molarity × Volume(L) ... Jun 1, 2007 ...
