Question
1b. Which of the following pairs of 0.1 M aqueous solutions would result in the formation of a precipitate upon mixing?
a) lead(II) acetate + potassium hydroxide
b) ammonium acetate + cadmium(II) nitrate
c) sodium chromate + nickel(II) iodide
d) strontium perchlorate + iron(II) sulfate
Indicate those pairs that result in a precipitate by their letter. IF none of them could be, then enter the word none. IF at least one can be, then your response should be a "word" made up of the letters a, b, c and d. The word may be one, two, three or four letters long. Make sure your choices are in alphabetical order. A response of bd would indicate that the second and fourth reactions result in precipitates. The response db would be marked wrong because WebAssign is looking for a word in alphabetical order.
1c. Which of the following pairs of 0.1 M aqueous solutions would result in the formation of a precipitate upon mixing?
a) lead(II) acetate + potassium nitrate
b) sodium chromate + ammonium phosphate
c) nickel(II) nitrate + sodium sulfide
d) strontium perchlorate + iron(II) chloride
Indicate those pairs that result in a precipitate by their letter. IF none of them could be, then enter the word none. IF at least one can be, then your response should be a "word" made up of the letters a, b, c and d. The word may be one, two, three or four letters long.
