Calculate the pH of a solution made by adding 24 g of sodium acetate, NaCH3COO, to 26 g of acetic acid, CH3COOH, and dissolving in water to make 200. mL of solution. The Ka for CH3COOH is 1.8 x 10-5 M. As usual, report pH to 2 decimal places.
if molarity of a 2000ml solution is 4.0M NaCl, how many moles of NaCl are dissolved in that solution.
Classify the substances CaCl2, CuSO4, NH3, C2H5OH according to the strongest solute-solvent interaction that will occur between the given substances and water during dissolution from the following choices
The solubility of barium fluoride, BaF2, is 3.15 x 10-3 M at 25 °C. Calculate the solubility product, Ksp, of both compounds.
How many Joules are required to heat 2 L of water in a pot from 20 degree C to the boiling point of water? The specific heat of water is 4.18 J/g. Degree C and the density of water is 1 g/mL
In a quality control analysis for sulphur impurity 5.6 g metal sample was burnt in a stream of oxygen and sulphur was converted into SO2 gas The SO2 gas then oxidizes to sulphate by using H2O2 solution towhich had been added 30 mL of 0.04M NaOH
