A 21.928 g sample of aqueous waste leaving a fertilizer manufacturer contains ammonia. The sample is diluted with 72.517 g of
water. A 11.823 g aliquot of this solution is then titrated with 0.1072 M HCl. It required 32.12 mL of the HCl solution to reach
the methyl red endpoint. Calculate the weight percent NH, in the aqueous waste.

Nconcentration refers to the molar concentration of an ion in solution. it may be identical to, or greater or less than, the molar concentration of the compound containing the ion that was used to make the solution. for soluble salts, the molarity of a particular ion is equal to the molarity of that compound times the subscript for that ion. for example, 1 m of alcl3 is 1 m in al3+ and 3 m in clโ. 1 m of (nh4)2so4 is 2 m in nh4+ and 1 m in so42โ. part a what is the concentration of k+ in 0.15 m of k2s? view available hint(s) nothing m m part b if cacl2 is dissolved in water, what can be said about the concentration of the ca2+ ion? view available hint(s) if is dissolved in water, what can be said about the concentration of the ion? it has the same concentration as the clโ ion. its concentration is half that of the clโ ion. its concentration is twice that of the clโ ion. its concentration is one-third that of the clโ ion. part c a scientist wants to make a solution of tribasic sodium phosphate, na3po4, for a laboratory experiment. how many grams of na3po4 will be needed to produce 550 ml of a solution that has a concentration of na+ ions of 0.700 m ? express your answer numerically in grams. view available hint(s) mass of na3po4 n a 3 p o 4 = nothing g provide feedback
