醋酸鈉一般以帶有三個(gè)結(jié)晶水的三水合乙酸鈉形式存在。在運(yùn)用的過程中，有時(shí)分會(huì)發(fā)現(xiàn)本來是白色的醋酸鈉的顏色會(huì)變?yōu)槠渌伾?，而液體醋酸鈉的顏色為淺黃色。

Sodium acetate generally exists in the form of sodium acetate trihydrate with three crystal water. In the process of application, sometimes found that the color of white sodium acetate will change into other colors, and the color of liquid sodium acetate will be light yellow.

1.醋酸鈉很容易溶于水，活性強(qiáng)，當(dāng)增加有其他顏色的金屬時(shí)，會(huì)出現(xiàn)醋酸鈉將其他顏色顯著的突顯出來，使全體的顏色改動(dòng)。

1. Sodium acetate is easily soluble in water and has strong activity. When metal with other colors is added, sodium acetate will highlight other colors and change all colors.

2.醋酸鈉制備過程中，很多是經(jīng)過離子反響或氧化發(fā)作，本體較活潑。一旦摻入重金屬元素在其間，由于這些便是雜質(zhì)離子，會(huì)使醋酸鈉晶格曲線歪曲變形以于失掉對(duì)稱性而發(fā)作效果。

2. In the process of preparation of sodium acetate, many of them go through ion reaction or oxidation attack, and the body is more active. Once the heavy metal elements are mixed in it, because these are impurity ions, the lattice curve of sodium acetate will be distorted, so that the symmetry will be lost and the effect will occur.

3.不同重金屬的特點(diǎn)不同，不同特點(diǎn)的醋酸鈉對(duì)雜質(zhì)的靈敏度不同，在摻入后，會(huì)有不同反響。

3. The characteristics of different heavy metals are different. Sodium acetate with different characteristics has different sensitivity to impurities, and will have different reactions after doping.

4.一般醋酸鈉本體是白色的，運(yùn)用中，難免會(huì)參雜其他物質(zhì)時(shí)分，一些重金屬的顏色比較重，會(huì)對(duì)白度發(fā)作顯著的效果影響。例如鉻、錳、鐵、銅、鉆、鈰、釩、鉛等等重金屬，構(gòu)成醋酸鈉雜質(zhì)，即便是很少的量就可以是醋酸鈉出現(xiàn)出重金屬的顏色。

4. In general, sodium acetate is white. When it is used, it is inevitable to mix other substances. When some heavy metals are heavy in color, it will have a significant effect on the whiteness attack. For example, chromium, manganese, iron, copper, cobalt, cerium, vanadium, lead and other heavy metals constitute sodium acetate impurities, even if a small amount of sodium acetate can appear in the color of heavy metals.

5.重金屬的參入量和不同特點(diǎn)的醋酸鈉，顏色的改動(dòng)狀況不相同。金紅石型的醋酸鈉對(duì)雜質(zhì)的影響更為靈敏，假如氧化鐵在金紅石型醋酸鈉中的含量大于0.003%時(shí)，就會(huì)出現(xiàn)顏色，而在銳鈦型醋酸鈉中的含量要大于0.009%才會(huì)發(fā)作顏色反響。

5. The content of heavy metals and the change of color of sodium acetate with different characteristics are different. Rutile sodium acetate is more sensitive to impurities. If the content of iron oxide in rutile sodium acetate is greater than 0.003%, color will appear, while in anatase sodium acetate, color reaction will occur when the content is greater than 0.009%.

醋酸鈉在水溶液中，是一種很弱的堿（pKb=9.24），不能在水中用強(qiáng)酸準(zhǔn)確滴定，因此需用非水滴定法。選擇適當(dāng)?shù)娜軇┤绫姿釀t可大大提高醋酸鈉的堿性。

Sodium acetate in aqueous solution is a very weak base (PKB = 9.24), which can not be accurately titrated with strong acid in water, so non-aqueous titration is needed. The alkalinity of sodium acetate can be greatly improved by choosing appropriate solvent such as glacial acetic acid.
