ClO2 is a yellow-green gas with irritating smell at normal temperature. its melting point is-59 ℃ and its boiling point is 11.0 ℃, which is easy to dissolve in water. it is slightly wet in industry. (1) make full contact with the reactants,Speed up the reaction rate and stir at reaction time;The instrument measuring the temperature is a thermometer,Therefore, the answer is: increase the contact area of reactants,Speed up the reaction rate;Thermometer;(2) the melting point of chlorine dioxide is low,To collect chlorine dioxide,Should be carried out at a lower temperature,So ice water bath should be used,Fully condensed,Reduce volatility;(3) the production of solute from solution,Generally, the method of evaporation, Crystal, filtration, washing and drying is adopted,?O,Therefore, the answer is: 2 Hot filtration;3 with 38 ℃ ~ Washing hot water at 60 ℃;4 Dry below 60 ℃;(4) 1 preparation of 100 c mol?-When the standard solution,100 vo
Qinyuan water purifier double water is good? The 'mainstream' water purification equipment in the market is roughly divided:'Front filter', built-in stainless steel filter, commonly known as 'front' is generally installed next to the water meter! The accuracy is about 90-100 microns if you filter some large filters in the water, such as some bugs, pipe rust, etc. Effect: generally, it is used in conjunction with the central water purifier, soft water machine, pure water machine, etc., mainly to prevent 'large particles' from blocking the supporting water purifier.It is not recommended to use it alone, with little effect.
