The reaction has made the solution more alkaline D. The pH value has no relation to the acid - alkali reaction 相关知识点: 试题来源: 解析 A。解析:在酸碱反应实验中,反应后pH值接近7。A选项说酸碱相互中和了,因为pH值接近7表示溶液接近中性,符合酸碱中和的结果。B选项说溶液变得更酸,与pH值接近7...
A. the acid and alkali can neutralize each other B. acid and alkali should not be mixed C. the reaction between acid and alkali is dangerous D. the neutral state is the best state 相关知识点: 试题来源: 解析 A。解析:A选项说酸和碱可以互相中和,这与实验结果“混合物变成中性”相符合。B选...
Using the techniques of conductometrie and potentiometric titrations of suspensions and aqueous and salt extracts, a study was made of the reaction of titanium carbide with hydrochloric acid and caustic soda. The absorption of the acid and the alkali by commercial titanium carbide is mainly due ...
When a strong acid reacts with a strong base (alkali), water and a salt are produced in a neutralization reaction. Some common strong acids are HCl, HBr, HI, and H2SO4. Common strong bases are NaOH, LiOH, and KOH. Answer and Explanation: ...
2. use the conditions forthe occurrence of the double decomposition reaction to correctly write thechemical equations involved in this chapterThere are many studentsremember the properties of acid and alkali and common salt, but exposure tospecific reaction specific substances, expressed by the chemical...
THE reaction of a solution of DNA with an alkylating agent such as dimethyl sulphate results in the production of acid as the alkylating agent is hydrolysed by water. To maintain the solution at a constant p H, the liberated acid must be neutralized by the continuous addition of alkali or ...
