Does table salt neutrilze the acidity in coffee?

Adding table salt to coffee does not neutralize the acidity in coffee. Table salt, also known as sodium chloride (NaCl), is a neutral compound and does not have acidic or basic properties. It does not react with the acidic compounds present in coffee, such as chlorogenic acids, to neutralize them.

The acidity of coffee is influenced by various factors such as the type of coffee bean, roasting level, and brewing method. While some people may perceive salt as counteracting the bitterness or sourness associated with coffee acidity, this effect is primarily due to the perceptual interactions between taste receptors on the tongue. Saltiness can alter the overall flavor profile and perception of acidity, but it does not chemically neutralize the acidic compounds in coffee.
