aqueous solution of transition metal aqua ions are often acidic. what factors must be taken into...
The aqueous solutions of the transition metal salts are acidic as a result of hydrolysis of their hydrated cations. The H2O in these hydrated cations can form different colors in the solution of colmplex ions by entering ligand exchange reaction with different ligands like CI, NH3 SO Cu2+ Fe2+ Cr3+ Ni2+ Co2+ Mn2+ Al3+ V3+ Sc3+ salts are separately a)Write down water-solubility / hydration reactions. b)Write down the hydrolysis reactions and explain the reason for the acidity according to the...

What are the concentrations of H3O+ and OH- ions (in M) in an aqueous solution with a pOH of 10.17? Is this solution acidic or basic? Explain your answer.
2.) Vinegar is an aqueous solution (homogenous mixture) of acetic acid and water (aqueous="aqua"= Latin for water). To simplify the calculations let us assume that all of the acetic acid in the vinegar reacts and there is some left over "excess" baking soda. The vinegar solution is a 5% acetic acid solution. If you look at the bottle of vinegar somewhere on there it probably says "5% acidity" or similar notation. Let us estimate that about 25.0 g of vinegar...
The reaction between bromate ions and bromide ions in acidic aqueous solution is given by the equation BrO3- (aq) + 5 Br – (aq) + 6 H+ (aq) à 3 Br2 (l) + 3 H2O (l) The table below gives the results of four experiments. Using these data, determine the orders for all three reactants, the overall reaction order, and the value of the rate constant. What is the value of k? What are the units of k? Experiment...
If you make a cathodic electrodeposition of a transition metal (any) ion dissolved in an aqueous solution, what would be an example of an effective anode and why?
Highly charged transition metal cations such as Cu2+ or Fe3+ tend to be_________in aqueous solution. Question 14 options: strong bases strong acids neutral weak acids weak bases
In acidic solution, bromate ion can be used to react with a number of metal ions. One such reaction is: BrO3−(aq)+Sn2+(aq)→Br−(aq)+Sn4+(aq). Since this reaction takes place in acidic solution, H2O(l) and H+(aq) will be involved in the reaction. Places for these species are indicated by the blanks in the following restatement of the equation:BrO3−(aq)+Sn2+(aq)+−→Br−(aq)+Sn4+(aq)+ −−−AWhat are the coefficients of the six species in the balanced equation above? Remember to include coefficients for H2O(l) and H+(aq) in the appropriate blanks. B)What are...
When the transition metal materials are dissolved in the aqueous solution (e.g. Cu(NO3)2, Fe(NO3)3, K2CrO4, NiSO4), the solutions have color(such as blue, green and yellow color). Why do transition metal complexes make colored compounds in solution? Describe the relevant theory and reasons.
