蘇打蘇打是Soda的音譯，化學(xué)式為Na2CO3。它的名字頗多，學(xué)名叫碳酸鈉，俗名除叫蘇打外，又稱純堿或蘇打粉。帶有結(jié)晶水的叫水合碳酸鈉，有一水碳酸鈉(Na2CO3·H2O)、七水碳酸鈉(Na2CO3·7H2O)和十水碳酸鈉(Na2CO3·10H2O)三種。十水碳酸鈉又叫洗濯蘇打、洗濯堿或晶堿。其其他性質(zhì)詳見(jiàn)本詞條的其他部分。 </p> <p> 在三種蘇打中，碳酸鈉的用途**廣。它是一種十分重要的化工產(chǎn)品，是玻璃、肥皂、紡織、造紙、制革等工業(yè)的重要原料。冶金工業(yè)以及凈化水也都用到它。它還可用于其他鈉化合物的制造。早在十八世紀(jì)，它就和硫酸、鹽酸、硝酸、燒堿并列為基礎(chǔ)化工原料--三酸兩堿之一。在日常生活中，蘇打也有很多用途，比如它可以直接作為洗滌劑使用，在蒸饅頭時(shí)加一些蘇打，可以中和發(fā)酵過(guò)程中產(chǎn)生的酸性物質(zhì)。貴州纖維素化工原料現(xiàn)貨</p><p
