The ph scale description this is an experiment from the practical chemistry project, developed by the nuffield foundation and the royal society of chemistry . Acids and bases exhibit different sets of properties that classify them along the ph scale concentration of hydrogen ions in aqueous acidic solutions classifies the substances bellow ph value of seven, neutral state, while hydroxide ions concentration classifies alkaline solutions above seven in the ph scale.
Mixing acids and bases can cancel out or neutralize their extreme effects a substance that is neither acidic nor basic is neutral the ph scale measures how acidic or basic a substance is. Acids and bases lab report lab-based introduction to the ph scale and the characteristics of acids and bases modified from vernier chemistry lesson 21 . Before studying the reactions of acids and bases, it is necessary to define exactly what each is this is not as easy as it sounds, and the acids and bases essay discusses in detail a subject covered more briefly here: the arduous task chemists faced in developing a workable distinction let us . Acids and bases are opposites but are alike in many ways bases are corrosive the ph scale is the way the acids, bases, and neutrals are measure in strength .

Chemistry project: acids and bases & the ph scale essay sample acids and bases are two groups of chemical compounds that generally have opposite characteristics.
I used red, and blue litmus paper to distinguish the acids apart from the bases but the use of the ph paper was the most reliable instrument used in my experiment to identify the acids and bases the ph paper identified hydrochloric acid and acetic acid as a 1 and a 2 on the ph scale, which states that both solutions are acids because they are . Neutralizing acids and bases the solution becomes less acidic and moves toward the middle of the ph scale this is called neutralizing the acid project the . Introduction this time, we will do some simple chemistry experiments to begin learning about acids and bases we will see how the acidity of substances is measured we will learn about some acid-base indicators we will produce ph indicating papers we will do a titration of vinegar we will search for natural indicating substances and we will determine the color scale of them.
