1. Prior to flocculation this requires pH to be adjusted to basic conditions through the addition of lime or caustic soda, this is the only way flocculation can occur
2. As part of post treatment... however my...
I got exactly the same as this except I put B for q.11.... Lime is added in the mixing tank prior to flocculation in order to create alkaline conditions... surely that has to be a correct answer??? also Im sure that any other pH adjustment comes AFTER chlorination since the hypochlorite ion...
They're from acidic environment...
The 2nd one is just a repeat of the story from Lavoisier-Davy-Arrhenius you know how sometimes they double up in the second column so if you have that information you're fine (Lavoisier- acids were compounds with oxygen Davy- acids had replaceable hydrogens...
yep cobalt complex ions
Co(H2O)6 +2 + 4Cl - --> CoCl4 -2 + 6H20
(sorry dont know how to do indices)
it turns pink on the left hand side and blue on the right hand side you can add chloride ions in the form of HCl and that will shift it to the right, add more water to shift it to the...
