ranges from 0-14. Litmus paper is an indicator used to tell if a substance is an acid or a base. The colour of the paper matches up with the numbers on the pH scale to indicate what kind of substance is being tested. For example, Vinegar is an acid and measures 2.4 on the pH ...

Associated Thought: Don't confuse weak and strong with dilute and concentrated: Weak and strong indicates the proportion of an acid or base which ionized (balance at equilibrium) Dilute and concentrated refer to the volume of acid and base dissolved (in a total solution) It is possible to hav...
Acid and Base pH Indicators pH range vs. color change for acid and base indicators - together with pKa and structures of the indicators. Acids - pH Values pH values of acids like sulfuric, acetic and more.. Alcohols and Carboxylic Acids - Physical Data Molweight, melting and boiling po...
Salt, in chemistry, substance produced by the reaction of an acid with a base. A salt consists of the positive ion (cation) of a base and the negative ion (anion) of an acid. The reaction between an acid and a base is called a neutralization reaction. Th
The effect of intracellular inhomogeneity on weak acid and base transmembrane distribution is examined. The significance of these variables for weak acid- or base-derived intracellular pH is discussed. 展开 关键词: Acid-base balance Intracellular pH Intracellular inhomogeneity Membrane permeability ...
Ratio of an Acid to its Conjugate Base: The ratio between the concentrations of an acid and its conjugate base determines the strength of the acid. The higher the value of the ratio, the less will be the dissociation of the acid and thereby the weaker it will be. ...

Buffer, in chemistry, solution usually containing an acid and a base, or a salt, that tends to maintain a constant hydrogen ion concentration. Ions are atoms or molecules that have lost or gained one or more electrons. An example of a common buffer is a
