WebMar 16, 2024 · The pH scale (pH) is a numeric scale used to define how acidic or basic an aqueous solution is. It commonly ranges between 0 and 14 but can go beyond these values if sufficiently acidic/basic. The pH value is logarithmically and is inversely related to the concentration of hydrogen ions in a solution.

WebDec 30, 2024 · NaCl is an ionic compound with a 1:1 ratio of sodium and chloride ions. The molecular weight of sodium chloride is 58.44 g/mol. 100 g of NaCl contains 39.34 g Na and 60.66 g Cl. It has a boiling point of 1,465 °C and a melting point of 800.7 °C. It is easily soluble in water and appears as a white crystalline solid. WebJan 17, 2024 · These coordinate covalent bonds weaken the the O-H bonds by pulling electrons towards the Al, and allow hydrogens to detach from the water molecules. This forms H3O+, meaning Al3+ acts as a weak acid. To solve for the pH, set up and ICE box with the concentration of Al3+ minus x, and the initial concentration of H3O+ (0 M) plus x.
