Question

Heat released in neutralization reaction of 500ml of 1N Hcl and 500ml of 1N Nh4OH is 1.36 k calories. the heat of ionisation of nh4oh is

Answer 1

Answer:

Explanation:

Number of grams equivalent to HCL = 500 ×0.1 / 1000 =  0.05

Numbers of gram equivalent to Nh4OH = 500 × 0.2 /1000 = 0.1

Sodium hydroxide is completely neutrelized by HCL

1 gram equivalent of sodium hydroxide  liberates 57.3 kj

 

    gram equivalent  of NaOH on neutrelization  will liberates

=     0.1 ×57.3 / 1 = 5.73 kj
