22.87 mL of a 0.1075 M NaOH solution are required to neutralize 0.300 grams of an unknown monoprotic acid. What is the molecular mass of the acid
Creatine is a by-product of muscle metabolism, and creatinine levels in the body are known to be a fairly realiable indicator of kidney function.
The total molarity of acid and conjugate base in this buffer is 0.100 M. A student adds 7.60 mL of a 0.330 M HCl solution to the beaker. How much will the pH change? The pKa of acetic acid is 4.760.
Assuming that the addition of the acid does not change the volume of the solution what is the pH of the acid/water mixture in the flask?
Thermodynamic measurements reveal that ?H° = -66.3 kJ/mol and ?S° = -73.2 J/mole*K at 40°C. What is the equilibrium constant for the binding reaction at 40°C?
The buffer has a concentration of 150 mMol ( 150 mM of KH2PO4 / 150 mM K2HPO4. The pKa of the drug ephedrine is 9.6. Will the drug have a negative, positive, or neutral?
How many grams of Cu(OH)2 can be produced from the reaction of 0.500g Cu with 30.0 mL of 3.0M NaOH? what is the limiting reagent?
