Find the `DeltapH(` initial `pH -` final `pH)` when `100 ml 0.01M HCl`

1.	Find the `DeltapH(` initial `pH -` final `pH)` when `100 ml 0.01M HCl` is added in a solution containing `0.1m` moles of `NaHCO_(3)` solution of negligible volume `(k_(a_(1))=10^(-7),k_(a_(2))=10^(-11)` for `H_(2)CO_(3)) :`A. 6+2 log3B. 6-log3C. 6+2log2D. 6-2log3
Answer» Correct Answer - A pH of `NaHCO_3` solution =9 (initial) Now `H^+ + HCO_3^(-) to H_2CO_3` `:.` no . of mmole of HCl remaining =1-0.1=0.9 mmole `:.` pH=-log `(9xx10^(-3))=-2 log 3+3` (Final)

How do biofertilisers enrich the fertility of the soil?
Read carefully the passage and select the correct answer out of given four options:Biofertilizers are organisms that enrich nutrient quality of the soil. The important sources of biofertilizers are bacteria, fungi and cyanobacteria. The symbiotic association of Rhizobium with the root nodules of leguminous plants is the common example. These bacteria convert atmospheric nitrogen into nitrogenous compound and fix in the soil.The organisms which enrich the nutrient quality of the soil are called(a) Microbes(b) Biofertilizers(c) Yeast(d) Biopesticides
