Question- Consider the following and briefly explain what would be the effect on the calculated analyte concentration; i.e. why would the calculated analyte concentration be higher, lower, or unchanged than the actual value if:
1) The last drop of base was not rinsed from the buret into the reaction flask?
2) The reaction flask contained traces of water in it before the acid was added with the volumetric pipet?
3) The volumetric pipet used to transfer the aid solution contained traces of water?
I want you to explain the chemistry in this problem
Standard reduction potentials are given on the next page. (a) Draw a diagram of the electrochemical cell, labeling all electrodes and solutions. (b) What is the pH in the Pt | H+ | H2 half-cell? (c) What is the value of the equilibrium constant fo..
Based on the data for step 2 of the experiment, predict what would happen if you performed step 3 of the experiment (how many sets of three drops of each of the HCl and NaOH would be needed until the buffering capacity is lost for the two solution..
1.00 mol HF and 0.500 mol NaOH are both dissolved in water making 1.00L solution. Calculate the pH of the solution
Explain If 1.2 M H2SO4 is used to titrate a 280.0 mL solution of 0.88 M ammonia (NH3), Explain what volume of acid is required to completely defuse the base. Every mole of this strong diprotic acid produces two moles of hydronium ions in water.
