Acid and Base Concepts

What is a basic solution?

• A basic solution is a solution to a linear programming problem where all constraints are equations and all variables are non-negative.

• A basic solution is a solution to a calculus problem where all variables are imaginary numbers.

• A basic solution is a solution to a quadratic programming problem where all constraints are equations and all variables are non-negative.

• A basic solution is a solution to a linear programming problem where all constraints are inequalities and all variables are negative.

List two properties of acids.

• Neutralizes bases, pH less than 7

• Forms covalent bonds, pH greater than 7

• Donates protons, pH less than 7

• Accepts protons, pH greater than 7

Define an acid.

• A substance that neutralizes bases.

• A substance that absorbs a proton in reactions.

• A substance that releases an electron pair in reactions.

Define a base.

• A base is the top support of a structure.

• A base is the middle support of a structure.

• A base is the ending point in a mathematical system.

• A base is the bottom support of a structure or the starting point in a mathematical system.
