Acid Base Titaration

You carry out the titration of a weak diprotic solid acid. You take 0.178 g of the solid acid and dissolve it in about 50 mL of distilled water. You titrate with 0.1005 M NaOH and arrive at the... more

Le Chatelier’s Principle and Chemical Equilibrium

The oxidation of NO to NO2 is exothermic.2 NO(g) + O2(g) -----> 2 NO2(g)If the system is at equilibrium and the temperature is increased, will the concentration of NO increase, remain the same... more

Le Chatelier’s Principle and Chemical Equilibrium

Nitrosyl bromide, NOBr(g), decomposes according to the equationNOBr(g) -------> NO(g)+ ½ Br2(g)a. If the equilibrium constant Kp= 0.15 at 350oC, will any net reaction occur if 1.2 atm NOBr, 0.7... more
