✔ 最佳答案
1) To prepare a hotter and more saturated Copper(II) Sulphate Solution
- Put a LOT of raw Copper(II) Sulphate crystal into a beaker and pour HOT boiling water onto them. Remember don't pour too much water into it - The water must NOT dissolve all the crystal (The trick is: more raw crystal less hot water!)
- Stir the mixture gently for 5 minutes
- While the mixture is still very hot, filter out the blue solution (the Filtrate) using funnel and filter paper

2) Now, quickly hang your Copper(II) Sulphate "seed" in the middle of the filtrate (saturated Copper(II) Sulphate Solution)

3) Next, wait until the solution cool down to room temperature. By that time, the crystal seed should grow much better! Placing the beaker in a windy place also helps faster crystallization

4) If you want to grow the crystal seed bigger, take it out, heat up the remaining filtrate, and use this heated filtrate as "hot water" and repeat steps (1-3)!

1)編寫一熱,更飽和的銅(II)溶液
- 放了很多原材料銅(II)硫酸鹽結晶成一個燒杯中倒入熱開水,並把他們。切記不要倒太多的水進去 - 不溶於水,必須所有的晶體(訣竅是:更多的原材料晶體少熱水!)
- 輕輕攪拌混合5分鐘
- 雖然混合物仍然十分炎熱,篩選出藍色溶液(過濾)使用漏斗和濾紙





2)現在,你快掛銅(II)硫酸鹽“種子”在中間的濾液(飽和銅(II)溶液)





3)接下來,等到解決冷卻至室溫。到那個時候,晶種應增長好多了!燒杯放置在有風的地方也有利於更快的結晶





4)如果你想壯大晶種越大,取出,其餘濾液加熱,並利用這一加熱濾液為“熱水”,並重複步驟(1-3)!

要加快硫酸銅既結晶速度,
便要加快溶液中的水蒸發的速度。

你可把溶液加熱。溶液的溫度愈高,水蒸發愈快。
你要維持空氣流通,可置一風扇增加 空氣流動速度。由於流動的空氣使流體與蒸發物質之間保持著較大的 濃度 差距,因此流動速度愈高,蒸發愈快。

(這些問題比較接近物理範疇呢~~)

可以多落一些藍凡,但不要太多
