When 5.0 ml of a 1.0 M HCI solution is mixed with 5.0 ml of a 0.1 M NAOH solution, temperature of the solution increases by 2^@C. which of the following can be predicted accurately from this observation?

Answer»

If 10 ml of same HCI is mixed with 10 ml of same NAOH, temperature RISE will be `4^@C`
If 10 ml of 0.05 M HCI is mixed with 10 ml of 0.05 M NaCl the temperature rise will be `2^@C`
If 5 ml of 0.I MHCI is mixed with 5 ml of 0.1 M `NH_3` solution, the temeprature rise will be less than `2^@C`
If 5 ml of 0.1 `MCH_3COOH` is mixed with 5 ml 0.1 M NaOH the temperature rise will be more than `2^@C`
