✔ 最佳答案
因為首先蘇打粉係鹼，同油污進行alkaline hydrolysis 同埋 saponification
令油污變成肥皂
因為肥皂係溶得到係水裏面
所以d油就可以用水洗走la...
加上肥皂既結構係一半溶油，一半溶水
所以肥皂溶油果一半會溶埋係剩番果d油裏面
另一半就溶係水裏面
再刷下d油既話
d油就會比肥皂eulsify左
同埋刷果陣出果d泡又可以幫助分解油...
結果剩番果d油就可以比水洗走la...

well sodium bicarbonate cause the dirt to dissolve in water
i dont think it has anything to do with the pH though
