The strength of an acid or base is determined by its dissociation in water; strong acids (like hydrochloric acid) completely dissociate, while weak acids (like acetic acid) do not. Strong bases (like sodium hydroxide) dissociate fully, whereas weak bases (like ammonia) only partially dissociate...
Coregistered measurements of the major ion species show that sulfuric acid (H2SO4), nitric acid (HNO3), and hydrochloric acid (HCl) determine greater than 98% of the acidity value. The latter, also described as excess chloride (ExCl), is shown mostly to be derived from postdepositional ...

Dissolution of Smectites in Hydrochloric Acid: II. Dissolution Rate as a Function of Crystallochemical Composition A correlation was made of crystallochemical data from 15 smectites with the half time of dissolution in 6 N hydrochloric acid at 96 degree C. From this a relation was developed. ...
Experiments were accordingly made with tap-water, adjusted to the required pH by the addition of traces of hydrochloric or sulphuric acids or of sodium carbonate, the normal pH of the water being about 7.3. While these results cannot be directly transferred to the case of fibre, owing to the...
Definition: Arrhenius Acid An Arrhenius acid is a substance that produces hydrogen ions (H+) or increases the hydrogen ion concentration when dissolved in water. Hydrochloric acid (HCl) is an example of an Arrhenius acid. When HCl is dissolved in water, it ionizes into H+ and Cl– ions: ...

If the food contains phosphorus, chlorine, sulfur and other minerals, in the human body will become phosphoric acid, hydrochloric acid, sulfuric acid and so on, and acidic. According to the kinds of minerals contained in food and the ratio of acidic elements and basic elements, they are ...
CausesHydrochloric acid and pepsin is secreted in the stomach (Kong & Singh 2008), it helps in breaking down and digesting food. Due to some weakness in the normal sphincter mechanism the acid may enter lower part of oesophagus. This causes heartburn. It commonly occurs after meals or when ...
