Interpretation Introduction

Interpretation:

The number of grains of Aspirin present in one tablet should be calculated by using given of NaOH solution.

Concept introduction:

Precipitation reaction:

If precipitate is formed, when two soluble salt solutions are mixed together is known as precipitation reaction.

The mass of precipitate is depends on the reactant masses.

Molarity:

The concentration of the solutions is given by the term of molarity and it is given by ratio between numbers of moles of solute present in litter of solution.

Molarity = No.molevolume (L)

Mole:

The mole of compound is given by the ratio between taken mass of the compound and molar mass of the compound.

Mole = Massof the compoundMolar mass of the compound

Mole:

The mole of the solute is calculated by multiplication of concentration of solution and volume of the solution and it is,

Mole = Concentration (M)× volume (L)

Another standard reference electrode is the standard calomel electrode: Hg2Cl2(s) (calomel) + 2e2 Hg() +2 Cl(aq) This electrode is usually constructed with saturated KCI to keep the Cl- concentration constant (similar to what we discussed with the Ag-AgCl electrode). Under these conditions the potential of this half-cell is 0.241 V. A measurement was taken by dipping a Cu wire and a saturated calomel electrode into a CuSO4 solution: saturated calomel electrode potentiometer copper wire CuSO4 a) Write the half reaction for the Cu electrode. b) Write the Nernst equation for the Cu electrode, which will include [Cu2+] c) If the voltage on the potentiometer reads 0.068 V, solve for [Cu²+].
