Being given the hydronium (or simply the hydrogen) ion concentration (molarity), one of the easiest properties of the solution to determine is its pH. The pH of a solution indicates the acidity (or basicity) of a given solution. The typical pH range of solutions is from 1 to 14, with 7 being neutral, 1 to 6 being acidic, and 8 to 14 being basic.
To determine the pH of a solution, the negative log (-log) of the hydronium/hydrogen ion concentration (molarity) of the solution is calculated. Thus (assuming that the given hydrogen ion concentration is in molarity (mol/L)),
pH = -log(

) or -log(

pH = -log (<span>7.94 × 10−6 mol/L)
pH = 5.13Because the pH is less than 7 (within the range 1 to 6),
then the black coffee solution is acidic. </span>

Question
What mass of Al₂O₃ form is produced if 25.00 g of aluminum (al) is reacted completely?, knowing the molar mass of Al₂O₃ is 102 g/mol?
Atomic mass of Al =27 and O = 16
The molar mass of Al₂O₃ = 102.
Mass of aluminium in 102 g of Al₂O₃ = 54 g
54 g Al => 102 g Al₂O₃
25g Al => x g Al₂O₃
x = 25*102/54 = 47.2 g Al₂O₃

Answer:
The oxygen atom in a water molecule is strongly electronegative. The atoms of the water molecule are held together by covalent bonds. water has nonpolar bonds, but it has a bent shape and is therefore polar.
