'''Karbit''' atau '''Kalsium karbida''' adalah [[senyawa kimia]] dengan rumus kimia CaC<sub>2</sub>. Karbit digunakan dalam proses [[las karbit]] dan juga dapat mempercepat pematangan [[buah]]. |
|||
| ⚫ | |||
[[Persamaan reaksi]] Kalsium Karbida dengan air adalah: |
|||
:CaC<sub>2</sub> + 2 [[air|H<sub>2</sub>O]] → [[asetilen|C<sub>2</sub>H<sub>2</sub>]] + [[Kalsium hidroksida|Ca(OH)<sub>2</sub>]] |
|||
Karena itu 1 gram CaC<sub>2</sub> menghasilkan 349ml [[asetilen]]. Pada proses las karbit, asetilen yang dihasilkan kemudian [[pembakaran|dibakar]] untuk menghasilkan [[panas]] yang diperlukan dalam pengelasan. |
