Many acids contain two or more ionizable hydrogens. There are two in carbonic acid, H 2 CO 3, and three in phosphoric acid, H 3 PO 4.For any such multiple hydrogen acid, the first hydrogen is most easily removed, and the last hydrogen is removed with the greatest difficulty.

Bei allen Experimenten müssen die Entsorgungshinweise für eingesetzte Chemikalien und erhaltene Stoffe geprüft werden. Chemikalienreste in Kleinmengen, die aus Experimenten anfallen, müssen in getrennten Behältern nach Gruppen gesammelt werden.
Si una persona se expone a la acetona, ésta pasa a la sangre y es transportada a todos los órganos en el cuerpo. Si la cantidad es pequeña, el hígado la degrada a compuestos que no son perjudiciales que se usan para producir energía para las funciones del organismo.

【浓度为0.1摩尔每升的磷酸钠溶液的PH是多少】 : Na3PO4水解有三级:PO4 3- + H2O = HPO4 2- + OH- Kh1 = Kw / Ka3 = 10^-14 / 2.2*10^-13 = 0.045HPO4 2- + H2O = H2PO4 - + OH- Kh2 = Kw / Ka2 = 10^-14 / 6.2*10^-8 = 1.61*10^-7 因为Kh1 > 1000 Kh2,所以可以忽略第二级及第三级的水解,以第一级计算:PO4 3- + H2O = HPO4 2- + OH- 0.1-x x xx2 / (0.1-x) = 0.045 解出x ...

In addition, it explains how to calculate the pH of a solution that consist of a mixture of H2PO4- and HPO4 2- which is basically a buffer solution and how to calculate the pH when one of those species predominate using a simple formula.

Hi Justin, yes the molarity comes into play in the calculations. For a strong acid, the pH equals the negative log of the molarity. For weak acids, the molarity determines the [HA] concentration that is used in the equation.
