When aqueous solutions of two acids have same concentration of common ions, they are called as

For two different acids with same concentration:

In aqueous solution nitric acid ionise to give two ions.

When the ph of a solution is 2 the hydrogen ion concentration is :

K_(a) for ascorbic acid (Hasc)is 5xx10^(-5) . Calculate the hydrogen in an aqueous solution in which the concentration of Asc^(-) ions in 0.02M .

The external solution having same concentration than the cell sap is called
