Chapter 16 Acids and Bases Arrhenius theory of acids and bases The Arrhenius concept: acids dissociate in water (aqueous solution) to produce hydrogen ions H+, and bases dissociate in water to give hydroxide ions, OH-. Arrhenius acid: HA (aq) H+ (aq) + A- (aq) Arrhenius base: MOH (...
Hydrogen Chloride B. Magnesium chloride C. Ethanol D. Potassium Hydroxide Correct Answer A. Hydrogen Chloride ExplanationHydrogen chloride (HCl) is a strong acid that dissociates in water to produce hydrogen ions (H+) and chloride ions (Cl-). In aqueous solutions, HCl donates a proton...
Perfectly pure water has a neutral pH of 7. Acids and bases neutralize each other because excess hydrogen ions combine with excess hydroxide ions to form water. These neutralization reactions also form various salts. For example, hydrochloric acid reacts with sodium hydroxide to produce water and ...
Which of the following statements applies to acids,bases,and salts!A.Their solutions conduct electricityB.They react with chemical indicatorsC.They cause litmus paper to change colourD.They react with metals to produce hydrogen gas请翻译一下问题和最后一个选项,下面那位在写些什么看不懂 答案 问题...
Which of the following is NOT a property of bases? 1. Bases taste bitter. 2. Bases react with acids. 3. Bases feel slippery. 4. Bases produce hydrogen ions, H+, when added to water. 5. Bases make indicators change colors. Identify the acids and bases in the given reaction: ...
Bases are substances which produce hydroxide ions in solution. Neutralisation happens because hydrogen ions and hydroxide ions react to produce water. Typical acids: hydrochloric acid (HCl), nitric acid (HNO3), sulphuric acid (H2SO4) Typical bases: sodium hydroxide (NaOH), potassium hydroxide (KOH...
Any aqueous (water-based) liquid can be classified as an acid, base, or neutral. Oils and other non-aqueous liquids are not acids or bases. There are differentdefinitions of acids and bases, but acids can accept an electron pair or donate a hydrogen ion or a proton in a chemical reactio...
Hydrogen ion and an anion of strong inorganic acids behaved differently on sorbent layer; generally H+ ion was stronger sorbed than A ion. Sorption and behavior of acid ions depended on the properties of a sorbent, solvent and acid, i. e. on an interaction of all components of the ...
Hydrobromic acid is a strong acid in aqueous solution. It dissociates almost completely into hydrogen ions and bromide ions when dissolved in water. It has a strong and distinctive odor that serves as a warning sign of its presence. The acid is commonly used in the production of organic compo...
6. the main ingredient of a mixture: to use rice as a base in cookery. 7. (Chemistry) a chemical compound that combines with an acid to form a salt and water. A solution of a base in water turns litmus paper blue, produces hydroxyl ions, and has a pH greater than 7. Bases are...
