Which of the following is not a type of ionic compound!A.saltB.acidC.baseD.water请翻译一下中文,.离子化合物是什么.那离子化合物和前三个选项有什么关系啊.
以下选项哪个不是离子态化合物?
Obviously,the answer is D
离子化合物由阳离子和阴离子组成的化合物.活泼金属(如钠、钾、钙、镁等)与活泼非金属(如氟、氯、氧、硫等)相互化合时,活泼金属失去电子形成带正电荷的阳离子(如Na+、K+、Ca2+、Mg2+等),活泼非金属得到电子形成带负电荷的阴离子(如F-、Cl-、O2-、S2-等),阳离子和阴离子靠静电作用形成了离子化合物.例如,氯化钠即是由带正电的钠离子(Na+)和带负电的氯离子(Cl-)组成的离子化合物.许多碱(如NaOH、KOH、Ba(OH)2 等)和盐(如CaCl2、KNO3、CuSO4 等)都是离子化合物.在离子化合物里阳离子所带的正电荷总数等于阴离子所带的负电荷总数,整个化合物呈电中性.多数离子化合物在固态(或晶态)时不能导电,而它的水溶液或熔化状态则能导电.离子化合物一般说来,熔点和沸点较高,硬度较大,质脆,难于压缩,难挥发.
共价化合物象氯化氢那样,以共用电子对形成分子的化合物,叫做共价化合物.如水H2O、二氧化碳CO2、氨NH3等都是常见的共价化合物.
SO,D是共价化合物.
