Alkalinity

“What’s the equivalent of inertia for resisting change in acidity in water?”

Water of different makeups reacts to a change in acidity in different ways. Just like how objects have inertia for resisting change in motion, water has Alkalinity for changing acidity levels. The higher a water’s alkalinity, the easier it can neutralize acid. The molecules carbonate (CO3), biocarbonate (HCO3), and hydroxide (OH) contribute to a substance’s alkalinity. Alkalinity is measured in milliequivalents per liter.
