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
it give sharp end point for coloured soln. even for those that are precipitate out in other volumetric titration
we standardize edta to make the soln stable complex
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)
(0.980 g H2SO4/g soln)x(1.84 g soln/mL soln)x(1 mol H2SO4/98.1 g H2SO4)x(1000 mL/1 L)=18.4 M

Iodine Tricholide (ICl3) is used as an Antiseptic ... for the Skin, 1% soln. & on Mucous membrane, 1:1000 to 1:2000 soln.
The word solution is usually abbreviated as soln. A solution refers to a homologous mixture of more than two substances.
The pigment of a flower can be extracted by first adding a soln. of ethyl alcohol to the petals of the flower taken in a test tube and then boiling it to 100 degree celsius in a water bath.The soln. obtained by filtering the above soln. contains the floral pigments
