It is of interest to decide if an analytical separation of the metal ions can be effected by selective precipitation of carbonates from a solution that is 9.09: 10 min me and 0.103 m in ca2+ mnco; caco; k-1.80x101 kp - 3.80109 to analyze this problem, answer the following questions. (1) what carbonate concentration is needed to precipitate 99.9% of the metal that forms the least soluble carbonate? (2) when 99.9% of the least soluble carbonate has precipitated, will all of the metal that forms the more soluble carbonate still remain in solutio yes (3) what is the upper limit on the carbonate ion concentration if the more soluble compound is not to precipitate? (4) if the co, is at this upper limit, what percentage of the metal that forms the least soluble carbonate remains in solution? submit answer 4 question attempts remaining

You can determine the rate of calcification at any given carbonate ion concentration as follows: draw a vertical line up from the x-axis at that concentration value until it intersects the red linear regression line; then draw a horizontal line from the intersection over to the y-axis to see what the calcification rate is at that carbonate ion concentration. if the seawater carbonate ion (co3 2-) concentration is 270 µmol/kg, a.what is the approximate rate of calcification, and b.approximately how many days would it take 1 square meter of reef to accumulate 30 mmol of calcium carbonate (caco3)

The concentration of pb²⁺ in a sample of wastewater is to be determined by using gravimetric analysis. to a 100.0-ml sample of the wastewater is added an excess of sodium carbonate, forming the insoluble lead (ii) carbonate (267 g/mol) according to the balanced equation given below. the solid lead (ii) carbonate is dried, and its mass is measured to be 0.1443 g. what was the concentration of pb²⁺ in the original wastewater sample? pb²⁺(aq) + na₂co₃(aq) -> pbco₃(s) + 2na⁺(aq)
