碳酸钠和碳酸氢钠之间的差异|比较类似术语之间的差异

碳酸钠（NA）₂co₃）通常称为洗苏打或苏打灰，是碳酸钠盐，而碳酸氢钠（nahco）₃）称为小苏打，是钠的另一种盐。这关键区别between sodium carbonate and sodium bicarbonate is that the碳酸钠含有钠，碳和氧原子，而碳酸氢钠含有钠，碳，氧原子以及氢原子。

碳酸钠and Sodium Bicarbonate are two sodium salts that are common in many products we use in homes. Sodium is a metallic element represented by the symbol Na. It is a soft, white in color, reactive metal that is not found naturally and is mostly found in the form of its oxides. It makes oxides when it comes in contact with air and also reacts quickly with water. The element sodium is essential for all living things and is useful in opposition to potassium ions. It allows for the transmission of nerve impulses and is thus we consider it as essential for human beings. Sodium is highly reactive and makes various compounds such as普通盐（NACL），小苏打（Nahco）₃），苏打灰（NA₂co₃), caustic soda (NaOH) etc.

什么是碳酸钠？

碳酸钠通常称为洗苏打水或苏打灰，是碳酸的钠盐。人们将其记得为水软化剂，因为它经常在房屋中有用。它具有碱性味道（带有冷却感觉）。我们可以提取Na₂co₃来自许多植物的骨灰。当需要大量时，我们可以通过称为solvay工艺的过程从普通的餐盐（NACL）中制成。在其许多工业用途中₂co₃对于制造玻璃很有用。当我们与碳酸钠一起加热二氧化硅和碳酸钙并突然冷却时，它会形成玻璃。这是一种特殊的玻璃。我们将其命名为苏打石灰玻璃。

Uses

由于碳酸钠是一个强大的碱，因此可以在游泳池中用来中和氯的作用。作为制作碱液卷的谎言代理也很重要。制作一些菜肴时，我们使用碳酸钠来改变食物表面的pH值，并赋予其棕色。在生物学研究中，我们可以将碳酸钠添加到沸水中，以洗涤身体的头骨和骨头部分，以从骨骼中去除肉。碳酸钠作为化学中的电解质很重要，因为它是一个非常好的导体，并且有助于电解过程。酸碱滴定also make heavy use of sodium carbonate.

Figure 01: Sodium Carbonate

As described earlier, in homes we use it as a water softener. Hard water contains ions of magnesium and calcium that add to the detergent disallowing formation of lather. Sodium carbonate soaks up these ions making the water soft and ideal for washing clothes. Moreover, we call it washing soda because of its ability to remove stains, oil and grease spots from clothes.

碳酸钠在食品工业中可作为食品添加剂，作为一种酸度调节剂。在砖工业中，它充当润湿剂，在铸造行业中，它充当了粘结剂。作为泡沫剂，它在多种牙膏中很有用。它甚至用于清洁银器。

什么是碳酸氢钠？

Sodium bicarbonate is another salt of sodium known as baking soda. This is actually sodium hydrogen carbonate since there is a hydrogen atom with a lack of one sodium ion. Sodium bicarbonate is a white solid but mostly found as a powder. It has the same alkaline taste of sodium carbonate and is highly soluble in water, which is why it is commonly found in spring waters. People often use it in names such as sodium bicarb or even only carb.

碳酸氢钠的主要用途是作为发酵剂烹饪。它与导致CO释放的其他物质反应₂which helps to make dough easily. This is why we call it bread soda. In fact, we can use sodium bicarbonate in the place of baking powder if acidic reagents are added. In earlier times, people used sodium bicarbonate for cooking as it made vegetables softer but now it is not in use as it destroys many vitamins and acids that are beneficial to us.

Sodium bicarbonate is an excellent exfoliating agent and hence it is very important for cleaning. It is commonly used in soaps and mouthwashes. Thus, it neutralizes the acid formation in the mouth and prevents teeth and gum decay.

碳酸钠和碳酸氢钠有什么区别？

碳酸钠是碳酸的钠盐，而碳酸氢钠（或小苏打）是钠的另一种盐。碳酸钠含有钠，碳和氧原子，而碳酸氢钠含有钠，碳，氧原子以及氢原子。这是碳酸钠和碳酸氢钠之间的关键区别。此外，碳酸钠具有化学式Na₂co₃and the molar mass is 105.98 g/mol. On the other hand, sodium bicarbonate has the chemical formula NaHCO₃摩尔质量为84 g/mol。

这difference between sodium carbonate and sodium bicarbonate can be highlighted based on the usage as well. The uses of sodium carbonate include using it as a water softener for laundering, in dyeing with fiber reactive dyes, for the manufacture of glass, paper, rayon, soaps and detergents. The uses of sodium bicarbonate include as a leavening agent for cooking, for the production of baking powder, as a pest control agent, to alkalinity is soil, etc.
