碳酸氢钠

An alkali such as sodium bicarbonate may relieve the pain to an even greater degree.

碱性物质如碳酸氢钠减轻疼痛的效果甚至更大。

You can also add softener; the typical softeners are sodium bicarbonate and sodium hydroxide.

也可采用加入软化剂方法，常用的软化剂为碳酸氢钠和氢氧化钠。

A solution of water, sodium bicarbonate, and acid.

苏打水：水、碳酸氢钠和酸的溶液

C. The quench is performed with aqueous sodium hydrogen carbonate and ethyl acetate.

三是演出的淬火、乙酸乙酯碳酸氢钠水溶液。

SPECTROMETRIC DETERMINATION OF PHOSPHORUS IN SODIUM HYDROGEN CARBONATE SOLUTION.

在碳酸氢钠溶液中可溶磷的光谱测定

Nitro-4-methylsulfonylbenzoic acid was prepared from 4-toluene sulfonyl chloride by the reaction of Alkylation (in the condition of sodium sulfite and baking soda), Nitrification (in the condition of nitric acid and vitriol) and Oxidation reaction (in the condition of nitric acid and catalyzer).

研究了以对甲苯磺酰氯为起始原料，首先通过亚硫酸钠和碳酸氢钠的水溶液进行烷基化、其次在浓硝酸和浓硫酸加热回流的条件下峭化、最后在浓硝酸和催化剂的条件下进行氧化，3步反应合成了玉米田高效除草剂甲基磺草酮的重要中间体2-硝基－4-甲磺酰基苯甲酸。

The experimental results show that the purity of product with sodium bicarbonate as catalyst is higher than that with triethylamine as catalyst.

实验结果表明，采用碳酸氢钠做缚酸剂得到的产品纯度更高，约为99.0%以上，颜色更加澄清透亮。

You can also use baking soda, wadded newspaper, clean kitty litter or charcoal.

你也可以使用碳酸氢钠、揉成团的报纸、干净的杂物包和木炭包。

Sodium bicarbonate is an alkaline salt which can undergo decomposition independently but will only yield sodium carbonate (Na2CO3, also known as washing soda) when heated. However, it produces an undesirable colour and texture when it reacts with fats and is therefore not suitable for use in the production of food.

碳酸氢钠属於碱性盐类，虽然自身也可以热裂解而产生反应，但所须温度高且会产生碳酸钠（Na2CO3，俗称洗涤碱，而与油脂反应产生不良的颜色与口感，并不适宜食品加工用。

Methods Under the acid condition, fluorine could be separated by distillation, then fluorine is absorbed by washing liquid. The electricity lead detection-ion chromatogram with Ionpac AS14 column was employed to determine the content of fluoride, 3.5 mmol/L of sodium carbonate-1.0 mmol/L of soda as the washing liquid at 1.2 ml/ mm.

氟在酸性条件下，蒸馏分离，蒸出的氟化氢被淋洗液吸收，采用电导检测－离子色谱仪和IonpacAS14色谱柱，3.5 mmol/L碳酸钠－1.0 mml/L碳酸氢钠为淋洗液，流量为1.2 ml/min，样品及标准系列在酸性条件下经水蒸气蒸馏－吸收，直接进样测定。
