ACIDS AND BASESAcids and bases are substances that form compounds and solutions with an electrical charge. When acids dissolve in water, they donate additional hydrogen ions to the solution. An acid, therefore, is a substance that increases the hydrogen ion concentration of a solution. A base, on the other hand, reduces the hydrogen ion concentration of a solution.The strength of acids and bases is measured by using a numeric scale known as pH, a measurement that represents the number of hydrogen ions in a solution, pH is measured with a pH meter or with paper strips that have color indicators. The pH scale runs from 0 to 14, with the midpoint at 7. A neutral solution, such as pure water, has a pH of 7.0. A pH value of less than 7.0 denotes an acidic solution, and a value above 7.0 denotes a basic, or alkaline, solution. The pH of a solution declines as the concentration of hydrogen ions increases; the lower the number, the more acidic the solution. For example, a solution with a pH of 4.5 is far more acidic than one with a pH of 6.0. The pH for bases, or alkalis, is above 7.0, and the higher the number, the greater the basicity or alkalinity. A pH of 8.5 is more alkaline than a pH of 7.5.The internal pH of most living cells is close to 7.0. Most biological fluids measure within the pH range of 6.0 to 8.0. There are a few exceptions, however, including the strongly acidic digestive juice of the human stomach, which has a pH of about 2.0. The chemical processes of living cells are very sensitive to the concentrations of hydrogenions. Biological fluids resist changes to their pH when acids or bases are introduced because of the presence of buffers, substances that minimize changes in the concentrations of these ions. Buffers in human blood, for example, normally maintain the blood pH very close to 7.4 because a person cannot survive very long if the blood pH drops to 7.0 or rises to 7.8.Acids and bases are used in food preparation and in industrial pro

- 主題:內(nèi)容豐富,但是盜版。地區(qū)并不偏遠(yuǎn)卻送貨極慢,浪費時間。
內(nèi)容沒錯,價格不貴,是我給三顆星的原因。 送的太慢,當(dāng)初急著復(fù)習(xí)用,卻等待甚久。 內(nèi)容上:閱讀的分類是非常實用的,雖然文章與實際篇幅出入大,但是熟悉題型和思路非常有用。看攻略說聽力快于實際考試,可以作為練習(xí),現(xiàn)在水平不夠,還沒有用。 紅色delta 的缺貨讓我非常無奈,網(wǎng)站建設(shè)實在需要完善,畢竟也是號稱中國網(wǎng)購圖書的先鋒,怎么覺得軟件建設(shè)像是新網(wǎng)站呢。加油。
- 主題:太離譜了,我買的這本書,但送到的是《托爾斯泰與陀思妥耶夫斯基...
怎么回事,從沒遇到過,怎么能送一本完全不相關(guān)的廉價書!希望網(wǎng)站協(xié)助辦理,不要這樣破壞自己的品牌呀
