Arrhenius Acid-Base Direct Titration Calculations: Key Concepts. An acid-base titration is used to determine the concentration of an acid or a base.
given 0.2038 gram sample of Ni(NH3)5CL2 dissolved in 0.050L of 0.1503M HCL. Calculate how much 0.09901M NaOH would be required to titrate this sample to a endpoint ? so i know that the HCL in excess converts all the Nh3 in the sample into NH4. so i think...
you know what to do .. here is the solution .. Molar mass of Ni(NH3)5Cl2 is 214.7 g/mole so we have...

Heres what we did: Provided with a standard 0.01M solution of sodium carbonate Exactly 25.0cm3 of the approximate 2M hydrochloric acid was very carefully diluted using a bulb pipette. The meniscus was exactly on the line of 25.0cm3 on the pipette. The...
moles of Na2CO3 = M x V = .01 mole liter ^-1 x .025 liter = 0.00025 moles we see from the equation that...
