conical flask

Specialized as part of their chemistry lesson, the children were told to heat different liquids in a conical flask.

化学课上有一部分内容是要求孩子们在一只锥形瓶子里将不同液体加热。

Thus, in a conical flask with small funnel, sample is decomposed by HNO_3-H_3PO_4-H_2O_2, using phosphoric acid of 20% as reaction medium, concentration of potassium borohydride is controlled at 2%.

以HNO3H3PO4H2O分解样品，选用20%的磷酸作反应介质；硼氢化钾浓度控制在2%。
