Concept explainers
(a)
Interpretation:
The charge density of an ion and the properties that affect it are to be determined.
Concept introduction:
An ion is the species that have a net electric charge due to loss or gain of electrons.
The cation is an ionic species with a positive charge. It has more protons as compared to electrons so the net charge on the cations is positive. Its
The anion is an ionic species with a negative charge. It has more electrons than protons so the net charge on the anions is negative. Its symbol is the element with a superscript of the negative charge.
(b)
Interpretation:
The order of increasing charge density is to be ranked.
Concept introduction:
The charge density is the density of charge around the ion. It is the ratio of ionic charge to the volume of ion. The ionic charge and size affect the charge density of the ions.
(c)
Interpretation:
The effect of ionic charge and size on the ionic heat of hydration is to be determined.
Concept introduction:
The enthalpy is the
The enthalpy change of hydration is the enthalpy change when one mole of the ionic species is dissolved in water to give a solution of infinite dilution. It is represented by

- we were assigned to dilute 900ppm in to 18ppm by using only 250ml vol flask. firstly we did calc and convert 900ppm to 0.9 ppm to dilute in 1 liter. to begin the experiment we took 0,225g of kmno4 and dissolved in to 250 vol flask. then further we took 10 ml sample sol and dissolved in to 100 ml vol flask and put it in to a spectrometer and got value of 0.145A . upon further calc we got v2 as 50ml . need to find DF, % error (expval and accptVal), molarity, molality. please write the whole report. thank you The format, tables, introduction, procedure and observation, result, calculations, discussion and conclusionarrow_forwardQ5.
