groundwater from a borehole has the following analysis: Calcium $75$ mg$/$l$,$ magnesium $40$ mg$/$l$,$ sodium $10$ mg$/$l$,$ bicarbonate $300$ mg$/$l and chloride $10$ mg$/$l$.($i$)$ determine whether the chemical analysis of this water is accurate, if not identify the most appropriate missing species and calculate its concentration. $($ii$)$ Draw a bar chart of the water analysis and compute the total hardness, carbonate hardness and non$-$carbonate hardness of the relevant species expressed as mg$/$l CaCO$3$
