calculate the EMF of the cell at 298 K

The process of decomposition of an electrolyte by passing electric current through its solution is called as

How can you use a flame test to distinguish between hard and soft water

A 0.50 g sample of a Group 2 metal, M, was added to 40.0 cm3 of 1.00 mol dm–3 hydrochloric acid (an excess).

equation 1 M(s) + 2HCl (aq) → MCl 2(aq) + H2(g)

When the reaction had finished, the resulting solution was made up to 100 cm3 in a volumetric flask.

A 10.0 cm3 sample of the solution from the volumetric flask required 15.0 cm3 of 0.050 mol dm–3 sodium carbonate solution, Na2CO3, for complete neutralisation of the remaining hydrochloric acid.

Calculate the total amount, in moles, of hydrochloric acid remaining after the reaction shown in equation 1.

amount = ... mol

Use your answers to (a) and (b)(iv) to calculate the amount, in moles, of hydrochloric acid

that reacted with the 0.50 g sample of M.

amount = ... mol

Use your answer to (v) and equation 1 to calculate the amount, in moles, of M in the 0.50 g sample.

amount = ... mol Calculate the relative atomic mass, Ar, of M and identify M.

Ar of M = ... identity of M = ...
