Webb26 apr. 2024 · PH is the measure of how acidic or basic a substance is. In humans, pH balance plays a role in keeping the body functioning optimally. The ideal pH of the body … WebbHaving a hot tub with high pH levels means that the total alkalinity is off. Alkalinity acts as a guard to pH and keeps it on a normal level. Once the total alkalinity levels change, then the pH levels change too. If you see the pH levels that are way above the normal levels, then you should add pH minus. A very common pH minus is sodium bisulfate.

Webb3 sep. 2024 · To refresh your memory, the pH scale tells us the acidity or basicity of a solution. The scale goes from zero to fourteen, with zero being the most acidic and fourteen being the most basic or alkaline. Seven is … The pH scale ranges from 0 to 14, with a pH of 7 indicating neutrality, values less than 7 indicating acidity, and values greater than 7 indicating basicity. The pH scale is based on the hydrogen ion concentration, with each pH unit representing a tenfold difference in hydrogen ion concentration. Visa mer In chemistry, pH , also referred to as acidity, historically denoting "potential of hydrogen" (or "power of hydrogen"), is a scale used to specify the acidity or basicity of an aqueous solution.
