Is kscn basic or acidic
Witryna11 wrz 2024 · Commercially available NaOH contains impurities of NaCl, Na 2 CO 3, and Na 2 SO 4, and readily absorbs H 2 O from the atmosphere. To determine the concentration of NaOH in a solution, we titrate it against a primary standard weak acid, such as potassium hydrogen phthalate, KHC 8 H 4 O 4. Other Reagents Witryna14 sie 2024 · From Table 16.8.1 and Figure 16.8.1, we can see that CN − is a stronger base ( pKb = 4.79) than acetate ( pKb = 9.24 ), which is consistent with KCN producing a more basic solution than sodium acetate at the same concentration. In contrast, the conjugate acid of a weak base should be a weak acid (Equation 16.8.1 ).
