The Acid Demand Value (ADV) test is used to quantify the amount of acid soluble material in sand. It has a special significance when FNB systems are involved because these acid soluble materials (usually soluble in the FNB acid catalyst) may not be evident in a simple water based pH determination. Since water is the suspension medium for the pH test, a pH reading will only show the presence

Because of this, the foundry industry developed an acid demand test which more accurately measure carbonate concentrations. It is known that when equal amounts of a neutral distilled water, hydrochloric acid, and sodium hydroxide are mixed, the pH will remain neutral. If an equal portion of sand is added to the water/acid solution, the carbonates within the sand will consume a portion of the
