Sodium and Water
Description
A violent and impressive chemical reaction occurs when the alkali metal sodium comes into contact with water. This experiment demonstrates the release of hydrogen gas, the intense heat generated during the process, and the shift in the solution’s pH level as it becomes basic, as evidenced by a suitable indicator.

Na + H2O: נתרן ומים (2014-05-03)
תגובה כימית אלימה ומרשימה מתרחשת כאשר המתכת האלקלית נתרן באה במגע עם מים. הניסוי מדגים את פליטת גז המימן, את החום הרב שנפלט בתהליך ואת שינוי ה-pH של התמיסה שהופכת לבסיסית, כפי שניתן לראות בעזרת אינדיקטור מתאים.

Why Is the Ocean Salty?
Credit: מכון דוידסון לחינוך מדעיThe salinity of the oceans stems primarily from the erosion of rocks on land by slightly acidic rain, which dissolves minerals and carries them through rivers into the sea. As water evaporates from the ocean surface, these salts are left behind, their concentration steadily increasing over billions of years. Additional sources of salt include hydrothermal vents on the seafloor and underwater volcanic activity.2:33
