Dissolving Sodium Hydroxide in Water May 2014
Description
The dissolution process of sodium hydroxide (NaOH) in water is clearly demonstrated, illustrating the breakdown of the solid crystal into free ions within the solution. This reaction is exothermic, accompanied by a significant release of heat, making it a classic example of energy changes in chemical processes. Monitoring this reaction allows for a deeper understanding of the relationship between crystal structure and solubility.
Original title
NaOH + H2O: נתרן הידרוקסידי ומים - המסת סודיום הידרוקסיד במים (3.5.2014)
תהליך ההמסה של נתרן הידרוקסידי (NaOH) במים מודגם בצורה ברורה, תוך הצגת הפירוק של הגביש המוצק ליונים חופשיים בתמיסה. תגובה זו היא אקסותרמית ומלווה בשחרור חום משמעותי, מה שהופך אותה לדוגמה קלאסית לשינויי אנרגיה בתהליכים כימיים. המעקב אחר הריאקציה מאפשר להבין את הקשר שבין מבנה הגביש למסיסותו.

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
