As shown in the figure, a classmate is the filter installation plan when doing the experiment of 'removing sediment in water'. try to answer: (1) when standardizing the operation, it is necessary in addition to the instrument in the picture. (1) glass rods should be used when filtering,Guide the flow of liquid,Observation diagram,Lack of glass rods;Therefore, the answer is: glass bar;Drainage;(2) iron frame and funnel are a and B respectively;Therefore, the answer is: a iron frame;B funnel;(3) it can be seen from the precautions of filtering and combined with the illustration,The obvious error in the figure is that the lower end of the funnel is not close to the inner wall of the beaker,Should be close to the Beaker wall;Funnel bottom pipe should be close to the Beaker wall;(4) if the filter paper is damaged and the liquid level is higher than the edge of the filter paper when filtering, the insoluble in the liquid can enter the beaker below,So that the leachate is turbid;The beaker that undertakes th
Front filter 20 micron and 80 micron which is good? It must be determined by whether the smaller the better can meet the needs, the comparison of prices, and the impact on the equipment. It's good to be suitable. Xinxiang kreys filtration technology department replied, thank you.
