It is probably because a part of the oxygen produced from the reaction of KmnO4 and HCl is used up in oxidising the HCl to Cl2 gas
Standardizing EDTA in complexometric titration is done to determine its exact molarity or concentration. This is important because the accuracy of the titration results depends on knowing the precise concentration of the EDTA solution being used. By standardizing EDTA, any errors in concentration can be corrected, ensuring accurate and reliable results in the titration process.
Conductometric titration is used in analytical chemistry to determine the endpoint of a titration by monitoring changes in electrical conductivity. It is commonly used to determine the concentration of ions in a solution, such as the determination of the calcium ion concentration in water or the acid content in a sample. Conductometric titration is also useful in studying complexation reactions and acid-base titrations.
Wash your beakers containg the 2 solns with water n rinse with the respective solns. Do the same 4 the burette n pipette. The titratn flask is 2 b washd only with water n NOT with any othr soln. Ensure that u add ur indicator in the titratn flask n not da soln beakrs. Take a pilot reading 1st. Whn u r ready 2 do da expt, add the soln 4rm the burette till ur pilot readng, then add dropwise till colour change persists.
MgCl2(soln) + 2NaF(soln) ------> MgF2(s) + 2NaCl(aq)
Only possible to calculate approximately (without knowing densities of all solutions) when 'percent' means 'gram per 100 ml' or 'ml per 100 ml'Solve the following equations to find V1 and V2:7% * V1 (ml) + 45% * V2 (ml) = 15% * 800 (ml)V1 (ml) + V2 (ml) = 800 (ml) [Especially this 2nd equation in an approximation]Outcome: 632 and 168 ml respectively, but this is an approximation! (due to the ignoring of volume contraction: mixing will result in LESS ml's than 800 ml, so concentration will be more than 15%)

The word solution is usually abbreviated as soln. A solution refers to a homologous mixture of more than two substances.
A soln wil be obtained.
A soln wil be obtained.
Salt soln.
A soln wil be obtained.
Soln No 1: 44-[{4+4}/4]=42 Soln No 2: Dummy answer (4 x 4 + 4 - 4 + 4) =4 (1X1 + 1 - 1 + 1) =4 2 =42
an instrument use to vaporize the all parts of solvent from soln on industrial scale.
it becomes 2m
