As the pH of a substance rises from 7, it turns from a weak base to a strong base. A strong acid such as HCl, when mixed with water, will separate into molecules of hydrogen ions and chloride ions. That is called dissociation. Strong acids dissociate more completely than weak acids, ...

Explain.Acid-base Reaction:A chemical reaction in which both acid and base take part to produce salt and water. In this reaction, the exchange of hydrogen ions occurs between chemical species for neutralization, so it is also termed a neutralization reaction....
Titration is used to find out the concentration of an acid or base using a known concentration of and base/acid solution. The titrant (solution of known concentration) is taken in burette and is added to a known volume of analyte (solution of unknown concentratio...
Zinc fingers are proteins that are characterized by the coordination of zinc ions by an amino acid sequence that commonly contains two histidines and two c
A new strategy for preparing ammonium-type ionic liquid (IL) by acid/base neutralization reaction was proposed. The method contributed to preparing hydroxi... Xiaoqi,Sun,Yang,... - 《Aiche Journal》 被引量: 87发表: ...
a bottle of sulfuric acid, and indicator paper. The objective of this practice is to verify that the ammonium chloride behaves as an acid or as a base against sulfuric acid and sodium hydroxide. The pH, concentrations, and reaction constants must be measured to obtain an amount of ammonium ...
18 This question is about reactions and uses of the weak acids methanoic acid, HCOOH, and ethanoic acid, CH2COOH.(a) A student adds magnesium metal to an aqueous solution of ethanoic acid, CH2COOH. A redox reaction takes place.Write the overall equation for this reaction and explain, in ...
for a weak acid ionizing in water is a double arrow, indicating that both the forward and reverse reactions occur at equilibrium. At equilibrium, the weak acid, its conjugate base, and the hydrogen ion are all present in the aqueous solution. The general form of the ionization reaction is:...
