Explain the statement "Water has bent geometry"
Water has bent geometry; that is, the H-O-H bond angle is approximately tetrahedral. Repulsion among the lone pairs and the bonds decreases this bond angle somewhat. (The actual bond angle is 104.5°.)
A sample of water contains: suspended matter = 100 mg; Ca(NO3)2 = 16.4 mg/L; MgSO4 = 24 mg/L; MgCl2 = 19 mg/L; NaOH = 40 mg/L and KOH = 56 mg/L. Calculate temporary, permanent and
Q. Analysis of water gave the following results H 2 SO 4 = 196Mg/L; MgSO 4 = 24Mg/L, CaSO 4 = 272Mg/L and NaCl = 25Mg/L. Water is to be supplied to the town of the popul
