氯化氢,是由一个氯原子和一个氢原子构成的分子化合物,化学式为HCl。它是一种易溶于水的无色气体,有着强烈的刺激性气味。该气体冗余水后形成的溶液就是我们经常提到的盐酸。实验室中一般用固体NaCl和浓硫酸发生反应或者把浓硫酸和浓盐酸混合来制备HCl气体。 氯化氢的理化性质 物理性质:无色、窒息性气味,熔点-114...

Cellulose constitutes a significant portion of a large amount of agricultural and forest residues, as well as urban waste derived from forest products (e.g. waste paper), and represents a potential for the production of ethanol, a liquid fuel. To realise this potential it is necessary to ...
Solubility Equation Determine the state or phase of each substance (gas=g, liquid=l, solid/non-soluble=s, aqueous/soluble=aq) in its undissociated form by using the solubility rules or a solubility table. KF(aq) + HCl(aq) = KCl(aq) + HF(aq) ...
The aim is to remove the HCl from waste gas streams. In this type of unit the liquid to gas ratio in the column is usually very high. Any heat of solution generated in the process will therefore be taken up by the liquid phase, thus avoiding the need for coolers. Increased ...
