Calculate the pH at the equivalence point for titrating 0.170 solutions of each of the following bases with 0.170 M HBr
a) hydroxylamine
b) aniline
How many moles of NaOH were required to neutralize the amount of KHP in Part b. d) What is the concentration of the NaOH solution?
chlorobutenedioic acids dehydrochlorinate to give acetylene dicarboxylic acid. The Z reacts about 50 times faster
Using what you know about acid/base chemistry, determine the immediate effect that two 325-mg aspirin tablets would have on the pH of the stomach. Assume your stomach is half a liter in volume.
A solution of salt (molar mass 90 g mol -1) in water has a density of 1.29 g/mL. The concentration of the salt is 35% by mass.
find the ph of the two equivalence points and the volume (ml) of 0.0414 M KOH needed to reach them in the titration of 17.3 mL of 0.130 M H2co3 (first equivalent point = ML KOH, and pH= )
Molecular and ionic equations, What would be the proper balanced molecular and net ionic equations for each of these neutralization reactions?
A reaction between methane and hydrogen sulfide to produce carbon disulfide and hydrogen gas was carried out. CH4 (g) + 2 H2S(g) → CS2 (g) + 4 H2 (g)
If 86.0 mL of .150 M HCL is needed to neutralize all the NH3 from a 2.25-g sample of organic material, calculate the mass percentage of nitrogen in the sample.
A bottle containing 315 g of cleaning solution is used for carpets. If the cleaning solution has a specific gravity of 0.850, what volume of solution was used?
In what direction do the functions point? What orbitals are"left" unused on the C atom?
A titration required 18.38 mL of 0.1574 M NaOH solution. How many moles of NaOH were in this volume?
The tank is first evacuated, and then it is connected to a 50.0 L cylinder of compressed nitrogen gas. The gas pressure in the cylinder, originally at 21.5 atm, falls to 1.55 atm without a change in temperature. What is the volume of the tank?
