Acids, Bases, & the pH Scale Acidic or Basic? Measuring the pH. Bibliography. Email. Print ... The pH of a liquid or solution is often an important piece of information in science. Measuring pH can be done simply and quickly using pH test paper, pH indicator sticks, or a pH meter.


The meter may have either a digital or an analog (scale and deflected needle) readout. Digital readouts have the advantage of exactness, while analog readouts give better indications of rates of change. Battery-powered portable pH meters are widely used for field tests of the pH of soils.


The pH scale runs from 0 to 14, with 0 being extremely acidic, 7 being neutral and 14 being extremely alkaline. SUBSCRIBE to the Fuse School YouTube channel for many more educational videos.


The pH scale and neutralisation The pH runs from 0 (strongly acidic) through 7 (neutral) to 14 (strongly alkaline). Salts are made when acids and bases react together.


Science >> Chemistry for Kids Acids and bases are two special kinds of chemicals. Almost all liquids are either acids or bases to some degree. Whether a liquid is an acid or base depends on the type of ions in it. If it has a lot of hydrogen ions, then it is an acid. If it has a lot of hydroxide ions, then it is a base. pH Scale
