Hydrochloric acid (HCL) is a colorless and highly pungent solution of hydrogen chloride and water. Once commonly referred to as muriatic acid or spirit of salt, this acid is a highly corrosive chemical compound with several applications in industry. It is also found in diluted amounts in the ...
Water is neither an acid nor a base. (a) True (b) False. Acids have a pH level of below 7. Base have a pH level of above 7. True or false? Buffer solutions are necessary to keep the correct pH for enzymes in many organisms to work. \\ A. True ...
The reaction between hydrochloric acid and sodium hydroxide is ___. A. endothermic B. exothermic C. neither endothermic nor exothermic D. impossible to determine 相关知识点: 试题来源: 解析 B。解析:文中提到 This reaction is exothermic,即盐酸和氢氧化钠的反应是放热反应。反馈 收藏 ...
What is the pH at the equivalence point when 1.0 M weak base B (K_b = 1.0 * 10^(-5)) is titrated with 0.50 M of strong acid, HClO4? Suppose you add hydrochloric acid to silver nitrate and get silver chloride and nitric acid. If hydrochloric acid is the limiting agent, how do yo...
The reaction between zinc and hydrochloric acid is an example of ___. A. combination reaction B. decomposition reaction C. displacement reaction D. double displacement reaction 相关知识点: 试题来源: 解析 C。锌和盐酸反应生成氯化锌和氢气,是一种置换反应,一种单质置换出另一种单质。选项 A 是化合...
8 When concentrated hydrochloric acid is added to an aqueous solution of copper(lI ) sulfate,the blue solution changes to green then yellow. The change in colour is due to C A the formation of chlorine in the solution. B the gradual replacement of the sulfate ion ligands by chloride ions....
Which is a stronger acid, hydrochloric acid ({eq}HCl {/eq}) or sulfuric acid ({eq}H_2SO_4 {/eq})? Acidity: The strength of an acid is the measure of how much dissociation will occur if the acid is dissolved in a solution. The higher the dissolution will result ...
It occurs when an acid reacts with a base to form a salt and water. The principle behind this reaction is based on the transfer of hydrogen ions (H⁺) from the acid to the hydroxide ions (OH⁻) from the base. For example, when hydrochloric acid (HCl) reacts with sodium hydroxide...
For example, when hydrochloric acid (HCl) reacts with sodium hydroxide (NaOH), the reaction is as follows: HCl + NaOH → NaCl + H₂O. In this reaction, hydrochloric acid is the acid, sodium hydroxide is the base, sodium chloride (NaCl) is the salt, and water (H₂O) is the pro...
The existence of a free mineral acid in a tissue or its secretions is of itself a phenomenon of sufficient interest to attract attention to its cause. For this reason the problem of the genesis of the hydrochloric acid of the gastric juice has never lacked investigators. In addition to the ...
