Witryna1 paź 2024 · Solution H3PO4 + NaOH. J’ai un exercice sur lequel j’ai une difficulté. Énoncé : On mélange 500 mL d’H3PO4 10^-2 M et 500 mL de NaOH. Les pKa de H3PO4 sont respectivement : 2,23 / 7,21 / 12,32. Le pKa le proche du pH étant pKa = 7,21 j’utiliserai ce dernier dans la formule du pH. Mon problème ce trouve là … NaOH (aq) + HCl (aq) → NaCl (aq) + H2O (l) In general, such neutralization reactions are represented by one simple net ionic equation: OH−(aq) + H+(aq) → H2O (l) This type of reaction with a strong acid releases heat, and hence is exothermic. Such acid–base reactions can also be used for titrations. Zobacz więcej Sodium hydroxide, also known as lye and caustic soda, is an inorganic compound with the formula NaOH.
