3:1, which will yield H3PO3 in a ratio of 3. If you combine97.995g (or1moles) ofH3PO4(molar mass = 97.995 g/mol) and11.333g (or0.333moles) ofPH3(molar mass = 33.998 g/mol) it will have a theoretical maximum yield of109.328g (1.333moles) ofH3PO3(molar mass = 81.996 g/mol)...
The Gibbs free energies of formation (ΔG o f ) were determined to be −3796.71 and −6314.63 kJ/mol, respectively. The solubility decreased with the increasing Pb/(Pb + Ca) molar ratios (XPb) of (PbxCa1‒x)5(PO4)3(OH). For the dissolution at 25 °C with an initial pH of...
After 24 h, the resin gels were retrieved and eluted in 10 ml of 1.4 M HNO3 and 0.1 M HF as described by Osterlund et al. (2010) and concentration of eluted W was determined by ICP-MS. The mass of W accumulated in the resin during the deployment time (M) was calculated using the...
If a pH meter were calibrated incorrectly (so that it read 7.5 when the pH of the solution was really 6.5), what aspects (molar mass, pKa(s)) of the determination would be incorrect?How can pH indicator strips determine the pH of a solution?How do you calculate the pH of ...
The molar mass of NaOH is 40.0 g. How many grams of NaOH do you need to make 1 liter of a 10% sodium hydroxide solution? One liter of caustic solution with a pH of 12.5, was reduced to a pH of 8.5, with 15 ml 98...
