The hydronium concentration, often represented as [H3O+], is the measure of the amount of hydronium ions in a solution. It's used to determine the acidity or alkalinity (pH) of a solution.
Think of hydronium concentration like the spiciness level in your favorite dish. Just as more chili peppers make a dish spicier, more hydronium ions make a solution more acidic.
Acid: A substance that donates protons (or hydrogen ions) when dissolved in water, increasing the hydronium ion concentration.
Base: A substance that accepts protons (or hydrogen ions) when dissolved in water, decreasing the hydronium ion concentration.
pH Scale: A logarithmic scale used to specify the acidity or basicity/alkalinity of an aqueous solution. It measures how much H3O+ is present.
