Carbon dioxide (CO2) gas dissolved in water can cause water to become acidic.The acidity of water from dissolved CO2 can be reduced by a base such as baking soda (sodium bicarbonate).
Aldosterone is a key steroid hormone critical for maintaining salt and water balance. It regulates the concentration of minerals, like sodium and potassium, in the fluid outside your cells. When your sodium levels drop, or potassium levels rise, your body signals your adrenal glands to release aldosterone into your blood. Aldosterone signals your kidneys to reabsorb sodium into the blood, and acts on your sweat glands to reduce sodium loss through sweat.
