Question - Write the reaction of crystal violet with HCl and explain why HCl quickens the elution of crystal violet
Please explain above problem in step by step manner so I can easily understand it
show an example of your Ka or Kb calculation for NaC2H3O2 given that the measured pH is 7.20 and the [H+] is 6.3 x 10^-3
190 ml of an hcl solution with ph of 2.60 is added to 200 ml of an hno3 solution. the resulting ph is 1.40. what was
If the energy needed to raise the temperature of the water to 29.0 degrees Celsius is obtained from the combustion of methane (CH4), what volume of methane, measured at STP, must be burned
SO2Cl2, decomposes when heated. The initial concentration of SO2Cl2 was 0.0248 mol/l if the rate constant is 2.2x10^(-2)/s, what is the concentration of SO2Cl2 after 2.0 hours? the reaction is first order. SO2Cl2(g)->SO2(g)+Cl2(g)
What is the concentration of the final solution obtained when 200.0 mL of a 0.00600-M solution of Red #40 dye is added to 400 mL of a 1.2 x 10^-2 solution of Red #40 dye to make a total volume of 600.0 mL?
it is given ab2 a 2b- a 0.07 m b- 0.09 m and pk 6.75 standard enthalpies of formation acetic and ab2 - 25.65 kcal
Compare in your mind 3 different liquids: pure ethanol, a 50% ethanol/water mixture and a 50 % ethanol/methanol mixture. Rank these three liquids in order of increasing Ptotal when each liquid is in equilibrium with its vapor at 25ºC.
One liter of O2, one liter of N2, and one liter of H2 are collected at a pressure of three atmospheres, each in a different container. The three gases are then forced into a single vessel of one-liter capacity,
Include drawings of each of the three ph cases for phenylalanine, and be certain to include the appropriate locations for charge on your molecular structure.
What is the molarity of a HCl solution if the reaction of 200 mL of the HCl solution with excess CaCO3 produces 14.0 L of CO2 gas at 725 mmHg at 18 degree celsius.
Compute the standard change in Gibbs free energy for the subsequent reaction at 25 degrees Celsius.
