Koolaid is made from a sugar/flavor mix that is dissolved in water, forming a solution. Solutions are evenly distributed mixtures where particles cannot be seen, unlike colloids where particles scatter light, or suspensions where visible particles remain dispersed. Concentration refers to how much solute is dissolved in a solvent - dilute solutions have little solute while concentrated solutions have more. Solubility is affected by temperature, pressure, and solvent type. Acids have a sour taste and turn litmus red while bases have a bitter taste and turn litmus blue. The pH scale measures acidity and alkalinity from 0-14, with 7 being neutral. Neutralization reactions involve an acid and base reacting to form
