What is an emulsifier? What is the definition of amine salts? What is corrosion? What is the difference between sodium chloride and sodium chlorite? What is the function of the salt bridge? What kind of electrolyte should be used in a salt bridge?
It is an inverted U-tube in which inert electrolyte is placed with agar-agar paste in a semi-liquid state. It is used to maintain the electrical neutrality of the solutions in the two half cells by adding inert electrolyte.Answer and Explanation: Functions of the salt bridge are as follows...
Pref. the anodes are made by forming an aq. soln. of CoCl2, NiCl2 NH4Cl, Na2SO3 and Sa2S2O3 and using this as electrolyte for deposition of the ternary Ni/Co/S mixt. of a (pref. Ni) grid, after which the anode is heated in air at 100-300 degrees C for 1 hour.PHILIPPE DEM...
A commercial Pt/C catalyst with a platinum content of 10 wt % (Johnson Matthey) was mixed with an aqueous 1M mixed solution of Cr(NO3)3.9H2O and NiCl2 and dispersed. The molar ratio of Pt:Cr:Ni in the mixture was 2:1:1. The mixture was then dried at 100° C. for one hour ...

Why does both an electrolyte and non-electrotype solution affect toxicity but only an electrotype solution affect conductivity? What is a non-electrolyte? Give some examples. What are some general physical properties of ionic compounds such as sodium chloride? Why don't ionic compounds have electri...
What ions are present in an aqueous solution of NiCl2?Calculate the mass of ammonium chloride (MM = 53.491 g/mol), in grams, that should be added to 500.0 mL of a 0.100 M NH3 solution to obtain a buffer with a pH of 9.50. Assume no volume change when the ammonium chloride is ...
