Low pressure acetylene is produced by reaction between calcium carbide and water.

Manav said: (Mar 15, 2014)  
Yes of course Low pressure acetylene is produced by reaction between calcium carbide and water.

Ya its calcium carbide and water.

Shubham said: (Jan 11, 2016)  
Low pressure consists of water and calcium carbide or calcium carbonate?

Kamaljit Singh said: (Apr 3, 2016)  
Yes. It is calcium carbide and water.

What's the difference between calcium carbide & calcium carbonate?

Kk Chauhan said: (Jun 30, 2016)  
CaC2 is calcium carbide and CaCO3 is calcium carbonate.

Pradeep said: (Jul 16, 2016)  
Please say which answer is correct.

Ankit Gupta said: (Oct 5, 2016)  
Calcium carbide is used.

Himanshu Nagar said: (Dec 12, 2016)  
Because it is made by carbide & water not carbonate.

Ayub said: (Mar 9, 2017)  
Calcium carbide is used to prepare acetylene.

Selvamani said: (May 31, 2017)  
It is Calcium Carbide.

Phaneendra said: (Jul 4, 2017)  
Low-pressure acetylene is produced by pouring Calcium carbide in water and high pressure acetylene is produced by pouring water in Calcium carbide.

Jonathan said: (Apr 13, 2018)  
Can't we also make use of calcium carbonate?

Mahi said: (Apr 21, 2018)  
Acetylene chemical formula is C2H2. So calcium carbide with water H2O only can make C2H2.

Santanu said: (Jul 20, 2018)  
Low pressure acetylene = water + calcium barbie(cac2).

Soustabh said: (Jun 2, 2019)  
Calcium Carbide not Carbonate.
