50 g caustic soda is completely converted into sodium chlorate and sodium chloride by the action of chlorine What weight of manganese dioxide and what volume of HCl (containing `300gL^(-1)`) were used for the production of necessary chlorine?

Text Solution

Verified by Experts

`underset(87g)(MnO_(2))+underset(4xx36.5g)(4HCl)toMnCl_(2)+underset(71g)(Cl_(2))+2H_(2)O`
`underset(3xx71g)(3Cl_(2))+underset(6xx40g)(6NaOH)to5NaCl+NaClO_(3)+3H_(2)O`
for 50 g of NaOH, the weight of `Cl_(2)` required
`=(3xx71xx50)/(6xx40)=44.25g`
Weight of HCl required`=(4xx36.5xx44.25)/(71)=91g`
Weight of `MnO_(2)` required`=(87xx91)/(4xx36.5)=54.226`g

    Read the paragraph carefully and answer the following questions: During gas analysis, the eudiometer tube filled with mercury is inverted over a trough containing. mercury. A known volume of the gas. or gaseous mixture to be studied is next introduced, which displaces an equivalent amount of mercury. Next a known amount, of oxygen in excess is introduced and the electric spark is passed, whereby the combustible material gets oxidized. The volume of carbon dioxide, water vapour or other gaseous products of combustíon are next determined by absorbing them in suitable reagents. The various reagents used for absorbing different gases are O_(3) rarr turpentine oil O_(2) rarr alkalino pyragallol CO_(2), SO_(2) rarr alkali solution [NaOH,KOH,Ca(OH)_(2)] A gaseous hydrocarbon requires 6 times its. owm volume of O_(2) for complete oxidation and produces 4 times its volume of CO_(2) . What is its formula?
