In the brown ring test, the dark brown ring is observed-----------------A. above the two layers of the liquidsB. at the junction of the two liquid’s layersC. at the bottom of the two liquid’s layersD. beside the meeting point of the two liquid’s layers

The ‘brown ring test’ is also known as test for------------A. Halide ionB. Sulphate ionC. Nitrate ionD. Ammonium ion

Brown ring test is salt analysis for the confirmation of nitrate ion. Magnetic moment of the complex formed is x BM comes out to be up to two decimal deduce that to single digit. For example if x = 2.73 add 2+7+3=12 and than again 1+ 2 = 3. So, answer will be 3.

22 Chlorine is bubbled through a cylinder containing aqueous sodium iodide and an immiscible layerof hexane.chlorine gasexcess gas outhexaneaqueoussodium iodideAs the bubbles pass through the cylinder, what is observed in the lower and upper layers?lower aqueous layer upper hexane layerA colourless solution becomes brown colourless liquid becomes colouredB colourless solution becomes brown colourless liquid is unchangedC brown solution becomes colourless colourless liquid becomes colouredD brown solution becomes colourless colourless liquid is unchanged

Liquid A is known to have a lower viscosity than Liquid B.Use this fact to predict the result of each experiment in the table below, if you can.experiment predicted outcome30.0mL each of Liquid A and Liquid B are poured through a funnel, and the times tA and tB needed to pour each liquid through the funnel are measured. tA will be greater than tBtA will be less than tBtA will be equal to tBIt's impossible to predict whether tA or tB will be greater without more information.35.0mL of Liquid A and 35.0mL of Liquid B are mixed together in a small beaker, and let stand for 30 minutes. A will form a layer on top of BB will form a layer on top of AThe liquids will form a homogeneous mixture.It's impossible to predict whether the liquids will mix without more information.

Learning goal 2: A scientist is investigating the properties of various mixtures made from two liquids. Liquid A is white and very runny. Liquid B is dark red and thick.Based on this information, predict the properties of the following two mixtures:5% Liquid A and 95% Liquid B80% Liquid A and 20% Liquid B
