2 years ago
9.08K
⚠️稀釋濃鹽酸安全注意事項:
1、首先戴上手套
2、室內開窗通風
3、讓自己位於上風處
ℹ️步驟:
1.事先準備好定量83cc稀釋用的蒸餾水倒入燒杯中
2.接著將10cc的玻璃滴管與塑膠唧筒相結合
3.小心打開濃鹽酸,注意鹽酸蒸氣飄散的方向
4.小心使用唧筒吸取10cc的濃鹽酸
(若能先將鹽酸倒入其他燒杯中再吸取可避免污染原液)
5.將濃鹽酸緩緩加入水中
6.鎖好瓶蓋後使用玻璃棒進行攪拌
7.最後進行 4% 鹽酸的分裝
ℹ️各品牌鹽酸稀釋為 4% 所需水量
(台灣)聯工化學GR級 35-37%:
🧪(36%)1cc鹽酸配上8cc的蒸餾水
(台灣)聯工化學ACS級 36.5-38%:
🧪(37%)1cc鹽酸配上8.3cc的蒸餾水(影片內的稀釋比例)
(台灣)城一化工EP級 32%:
🧪(32%)1cc鹽酸配上7cc的蒸餾水
🤔一份鹽酸要多少倍的蒸餾水來稀釋?
Ⓜ️公式:(既有鹽酸濃度/目標鹽酸濃度)-1
範例:36%的鹽酸 10ml,要多少蒸餾水來稀釋成 4%?
計算:36/4=9,9-1=8
答案:一份36%的鹽酸要8倍的水來稀釋,所以 10ml鹽酸要加入 80ml的蒸餾水中稀釋成 4%的鹽酸
ℹ️影片內器材料表
1.玻璃滴管10ml
2.塑膠吸管唧筒10ml
3.燒杯500ml
4.玻璃攪拌棒25cm
5.安全手套
6.量筒100ml
7.蒸餾水
8.聯工化學ACS級鹽酸 36.5-38%
