Reason:- Titration of strong acid against base
1aiv)2HCL(aq)+ x2Co3 -> 2 x CLaq + H20(aq) + CO2(g)
Molar mass of HcL = 1+35.5
Con of A is moldm^-3 =
Con of A of gdm^3/molar mass in gdm^3
using CAVA/CBVB = a/b
CA = 0.200mol/dm^3
VA = 26.20cm^3
Cb = ?
VB = 25.0cm^3
a = 2mols
b = 1mol
0.200mol/dm^3 x 26.2cm^3/Cb x 25.0cm^3
Cb = 0.200×26.20×1/25.0×1
Cb = 5.24/25.0mol/dm^3
Cb = 0.2096mol/dm^3
Conc. of B in gdm-3/Conc. of B in mol/dm-3
Relative atomic mass of X
Sample X is a soluble salt
A gas is evolved. The gas turns red moist litmus blue.
It forms white fumed when NaOH solution was added was added
CO3 gas is CO3^2-
The solution is alkaline
(NH4)2CO3(aq)+2NaOH(aq) >> Na2CO3(aq)+2NH3+2H2O(g)
REAGENTS: Adition of KSCN Solution
(Fe3+) Blood red colouration
REAGENT: Addition of NaOH solution in drop till excess
(Fe2+): Dirty green gelatineous precipitaye which is insolube in excess NaOH.
(Fe3+): Reddish brown gelatineous precipitate which is insolube in excess NaOH.
REAGENT: Addition of K2Fe(CN) solution
(Fe2+): It forms a dark blue precipitate
(Fe3+): A deep red colouration
i)NH4CL and AgNo3

REASON WHY STUDENTs FAIL
(1) Cheap/fake runz:
Alot of website are out there gving free or fake runz. imagine such a site not considering the results of students, compose fake answer or give the students fake runz. Most of the fault goes to students risking their own exams for cheap/free runz.
(2)Waiting to get free runz when we post it:
Normally, we do post answer late on the site for those that cant pay for the runz,
obj posted 10mins to the end,
theory posted 20mins to the end.
Tell me how do you want to pass by waiting for free answers when those that paid for the runz has finished, you are just starting.
What you dont know is that nothing is free, even in freetown. Learn how to pay for what you need most. Be wise and try harder to pass
