Club soda is just water with a few add-ins: carbon dioxide for carbonation and “mineral-like” ingredients such as sodium bicarbonate, sodium citrate, and potassium sulfate.

club soda 只是添加了一些添加剂的水：用于碳酸化的二氧化碳和“类似矿物”的成分，如碳酸氢钠、柠檬酸钠和硫酸钾。

So bakers started using chemical leavening agents like baking soda, which, if we were to use the actual chemical name, we would just call it sodium bicarbonate.

因此，面包师开始使用小苏打等化学发酵剂，如果我们要使用实际的化学名称， 我们会称之为碳酸氢钠。
