Question

1. For the coordination compound [Ti(H2O)6]Cl2
a) Determine the oxidation state of the titanium
b) How many d electrons does the titanium atom have in this compound?
c) Name the compound
d) The splitting energy for this compound is 58.0 kcal/mol of photons. What color is this compound? (Hint: what color is absorbed?). Show all of your calculations and clearly give your reasoning

I got a) +2 because 2 chloride counter ions which needs a +2 charge to balance it out, had an healthy debate with a classmate who insisted it was one of the rare cases where it was a 0 charge, but according to the book a 0 charge didn't make sense to me...

b) 2 because of column its in and etc

c) hexaaquatitanium(II)chloride

d) something like 491nm so blue/green

double checking my work
