求摩尔浓度MCALCULATE THE MOLARITY OF AN ACETIC ACID SOLUTION WHICH IS 2% IONISED, THE PKA OF ACETIC ACID IS 4.74 相关知识点: 试题来源: 解析 4.74是指醋酸在水中的电离程度,通过这个数可以算出醋酸根的电离浓度再除以2%应该是他的浓度吧。10的-4.74次幂除以2%就是他的浓度(M) 不知道对不对。

For example, if 0.1000 mole or 5.905 g of acetic acid (HC2H3O2) is dissolved in 1.000 liter of solution (H2O), the solution will be 0.00134 mole/liter in H3O+, 0.00134 mole/liter in C2H3O2−, and 0.0987 mole/liter in un-ionized HC2H3O2. Chemically, this partial dissociation can be ...

Molarity (M), molality (m) and the Colligative properties The molarity of a solution is the number of moles of solute per liter of solution. The symbol for molarity is M. Thus a 3.0 molar solution of nitric acid, abbreviated 3.0 M HNO 3 , contains 3.0 moles of HNO 3 per liter of ...

For a solvent like ethanol where the density is 0.789 kg/L, a 1 M solution would be 0.789 m. The important part of remembering the difference is: molarity - M → moles per liter solution molality - m → moles per kilogram solvent

If you look closely at a bottle of vinegar, you will find that it is a solution of acetic acid. Similarly, bleach is a solution of sodium hypochlorite. All of these examples have both a solute and a solvent. The solute is the material that is dissolved while the solvent is whatever it...
