Could a mixture of pepper and water also be called a solution?

No, a mixture of pepper and water would not be considered a solution. In chemistry, a solution is a homogeneous mixture where one substance (the solute) is dissolved in another substance (the solvent). In this case, pepper does not dissolve in water, so it would not form a solution. Instead, it would be considered a suspension, where the pepper particles are suspended in the water but do not dissolve.
