One Strip - One Dip - One Match Only one color to match for a clear and positive result. Hydrion pH papers provide a simple fast and reliable method of pH measurement. Just dip paper and match to the color chart. Tap, pond and rain water should be tested using Hydrion Lo-Buff Lo Ion pH Test Paper. Atoms, Ions and pH The atom is made up of neutrons which have no charge, protons which have a positive charge, and electrons which have a negative charge. Atoms always have an equal number of electrons and protons, so the charges cancel each other out. Ions If an atom picks up an electron (-), it becomes negatively charged; there are now more electrons than protons. If an atom loses an electron (-), it becomes positively charged; there are now more protons than electrons. Atoms with electron imbalances are called ions. Acids Acids in water separate into ions, and the positive ion is hydrogen (H+). When hydrochloric acid (HCl) mixes with water, it separates into positive hydrogen (H+) and negative chlorine (Cl-). Hydrogen (H+) combines with water (H2O) to make hydronium (H3O+). Bases Bases in water also separate into ions, and the negative ion is hydroxide (OH-). When the base sodium hydroxide (NaOH) mixes with water, it separates into positive sodium (Na+) and negative hydroxide (OH-). What is pH? pH is a scale measuring the acidity or alkalinity of a solution. The scientific definition is 'the negative logarithm of the Hydrogen ion concentration'. The pH scale is a measurement of the concentration of acid or base a substance contains and is calculated by determining the concentration of hydrogen ions (H+). Hydrogen Ions High hydrogen ion amounts indicate high acid concentration, low hydrogen ion amounts indicates a basic or alkaline concentration. The pH scale runs from 0 to 14 with 0 being the most acidic, 7 neutral, and 14 being the most alkaline or basic. It is a logarithmic scale, based on powers of 10, so that 1 pH unit change equals a 10 fold change in H+ ion concentration! A pH of 6 is ten times more acidic than a pH of 7. |
