Investigating iron thiocyanate requires several chemicals which must be used with caution. using knowledge of these chemicals, select whether the following statements are true or false. when handling hno3, it is important to wash your hands frequently since hno3 is corrosive and can cause burns. to dilute an acid, always add water to add while slowly stirring. fe(no3)3 should be handled with caution because it is an oxidizer and can irritate the skin. kscn is completely nontoxic if kscn is strongly heated it will cause the evolution of cyanide gas. kscn, if combined with a strong base, will also cause the evolution of cyanide gas.

1. suppose a reaction mixture, when diluted with water, afforded 300 ml of an aqueous solution of 30 g of the reaction product malononitrile [ch2(cn)2], which is to be isolated by extraction with ether. the solubility of malononitrile in ether at room temperature is 20.0 g/100 ml, and in water is 13.3 g/100 ml. what weight of malononitrile would be recovered by extraction with (a) three 100-ml portions of ether and (b) one 300-ml portion of ether? suggestion: for each extraction, let x equal the weight extracted into the ether layer. in part (a), the concentration in the ether layer is x/100 and in the water layer is (30 x)/300; the ratio of these quantities is equal to k 20/13.3.
