Question 7 of 31 Submit What is the pH of a 0.370 M solution of Ca(NO2)2 (Ka of HNO2 is 4.5 x 10-4)?
2. What is the pH of the resulting solution of Ca(OH)2 dissolved in a solution of 0.250 M CaCl2? Ksp Ca(OH)2 -4.86 x10
A solution of Ca(OH)2 has a measured pH of 12.50. What is the molar concentration of the Ca(OH)2 in the solution? What is the molar concentration of Ca(OH)2 if the solution is diluted so that the pH is 11.30? Ca(OH)2 in the original solution = × 10 M Ca(OH)2 in the diluted solution = × 10 M
Will Ca(OH)2 precipitate from solution if the pH of a 3.0×10−2 M solution of CaCl2 is adjusted to 8.0? Will Ag2SO4 precipitate when 100 mL of 4.0×10−2 M AgNO3 is mixed with 10 mL of 5.0×10−2MNa2SO4 solution?
