吸收热量增加,从而增加动能的运动速度和反应。在水里,然而,第一个打破氢键吸收热量的速度,而不是增加运动。因此。更多的热量必须应用水的温度升高的温度升高一个nonhydrogen-bonded液体。事实正相反作为冷却水。因此,水更容易建立保持不变 when anic salts such as sodium chloride (NaCl) are dissolved in water, they undergo dissociation, or ionization. That is, they break apart into ions. Substances called acids and bases show similar behavior. 当无机盐如氯化钠(盐)溶解在水中,他们经历了分离、或游离。也就是说,他们分裂成离子。物质称为酸和碱显示类似的行为。 An acid can be defined as a substance that dissociates into one or more hydrogen ions (H+ ) and one or more negative ions (anions). Thus, an acid can also be defined as s proton CH+ ) donor. A base dissociates into one or more positive ions (cations) plus on or more negatively charged hydroxide ions (OH- ) that can accept, bine with, protons. Thus, sodium hydroxide (NaOH) is a base because it dissociates
