Solutions with more hydroxide ions (OH-) than hydrogen ions (H+) are considered basic or alkaline. These solutions have a pH greater than 7. They can be formed by adding a base (such as NaOH) to water.
The more acidic of two acidic solutions has more H+ ions per liter.
H3PO3 is a dibasic acid because it has two replaceable hydrogen ions that can be ionized in a solution to form hydrogen ions (H+) and a phosphate ion (H2PO3-). This allows it to donate two protons and form two acidic solutions.
When two aqueous solutions are combined in a precipitation reaction and no precipitate is formed, it means that the ions in the solutions do not react to form an insoluble compound. Instead, they remain in solution as dissolved ions. This occurs when the ions present do not have a strong tendency to form insoluble compounds.
The electrolyte solutions in a galvanic cell contain ions that allow for the flow of electric current between the two half-cells. These ions help maintain charge balance and facilitate the chemical reactions that generate electricity.
An arrhenius acid is, by definition, a solution with a higher concentration of H+ ion than OH-.

An arrhenius acid is, by definition, a solution with a higher concentration of H+ ion than OH-. So any arrhenius acid will fit this definition. Two common acids are Lemon juice and vinegar.

Separating mixture refers to the separation of more than two solutes or solutions.
A homogenous mixture of two or more substances that are not solutions is a colloid. Colloids have particles that are larger than the particles in a solution, but still do not settle out over time. Examples of colloids include milk and fog.
Write the quadratic equation in the standard form: ax2 + bx + c = 0 Then calculate the discriminant = b2 - 4ac If the discriminant is greater than zero, there are two distinct real solutions. If the discriminant is zero, there is one real solution. If the discriminany is less than zero, there are no real solutions (there will be two distinct imaginary solutions).

If the discriminant of the quadratic equation is greater than zero then it will have two different solutions. If the discriminant is equal to zero then it will have two equal solutions. If the discriminant is less than zero then it will have no real solutions.
