Experiment Acids‚ Bases‚ and Neutrals Problem Are common house-hold products pH balanced and neutral? Information Gathered pH measures how acidic or alkaline a solution is. The pH scale ranges from 0-14. Solutions that range from 0-6 are considered to be acidic. Solutions that are on the acidic end of the scale are low in pH‚ high in hydrogen ion‚ and low in hydroxyl ions. An acid has a sour taste‚ hence‚ will react to metal and will be corrosive; therefore‚ they are considered as an electrolyte
