Atago 3354 QR-NaOH, Digital Suction-Type NaOH Refractometer, Sodium Hydroxide, NaOH : 0.0 to 38.0% Measurement Range

Not rated yet
0

 

Sodium hydroxide, also known as caustic soda or lye, is often prepared as solutions at different concentrations for a number of applications.The QR-NaOH allows the users to measure the concentrations without coming in contact with this alkali. Just plain tap water is sufficient for cleaning and zero-setting.

Sodium hydroxide, also known as lye and caustic soda,[1][2] is an inorganic compound with the formula NaOH. It is a white solid ionic compound consisting of sodium cations Na+  and hydroxide anions OH−

Sodium hydroxide is a highly caustic base and alkali that decomposes proteins at ordinary ambient temperatures and may cause severe chemical burns. It is highly soluble in water, and readily absorbs moisture and carbon dioxide from the air. It forms a series of hydrates NaOH·nH 2O. The monohydrate NaOH·H 2O crystallizes from water solutions between 12.3 and 61.8 °C. The commercially available "sodium hydroxide" is often this monohydrate, and published data may refer to it instead of the anhydrous compound. As one of the simplest hydroxides, it is frequently utilized alongside neutral water and acidic hydrochloric acid to demonstrate the pH scale to chemistry students
