What are the properties of a basic solution?
Another property of basic solution is electrical conductivity. The dissociation of the base into ions gives the solution the capability to conduct an electrical current. The electrical conductance can be used to measure the pH of the solution by digital instruments. Basic solutions can also be identified by their qualitative properties.
What is the pH of a basic solution?
A basic solution is an aqueous solution with a higher concentration of OH-ions than H+ions. To put it another way, it's an aqueous solution with a pH greater than 7. Acidic pH is below 7, neutral pH is 7, and basic pH is above 7. pH is the hydrogen ion concentrations, so the pH range of bases are 7-14.

Is there a fundamental lower limit for hydronium?
there is no fundamental lower limit. there is no fundamental lower limit. As this is simply the negative log of the hydronium concentration, each pH unit descended is simply an order of magnitude greater for hydronium concentration, so even at −1, which means 10M in hydronium, there is no theoretical limit at this point.
Is the pH scale the same as the concentration of hydronium ions?
The concentrations are the same. There is not enough information. Solution A. The pH scale measures the concentration of hydronium ions in solution. Lower pH values correspond to higher concentrations of hydronium ions. Since solution A has a lower pH, it has a greater concentration of hydronium ions.
