Is HClO4 classified as a strong acid, weak acid, strong base, or weak base? Explain. The conjugate base of a weak acid is a weak base, why? The substance HClO4 is considered: A. a weak acid. B. a weak base. C. a strong acid. D. a strong base. E. a neutral compound....
Describe the following as being a Bronsted acid, base, or both: a) H2CO3 b) HCO3-1 c) CO3-2 What is the chemical formula for the base cesium hydroxide? What does NaOh do in organic chemistry? What is the conjugate base of HClO4?
What is the pH at the equivalence point when 1.0 M weak base B (K_b = 1.0 * 10^(-5)) is titrated with 0.50 M of strong acid, HClO4? What is the pH of a 0.01 M solution of hydrochloric acid? How do you calculate bicarbonate concentration from pH?
What is the molarity of the acid given 18.2 mL of HClO4 is neutralized in a titration by 25.1 mL of a 0.382 M Ca(OH)2 solution? Please explain steps. What would be the molarity of a solution obtained when 50.0 mL of 3.00 M HCl acid solution is diluted with 70.0 mL of water?
Is HNO3 a base or acid? If you see any other acid or base than one of these strong ones it will be a weak acid or base (unless I specifically say otherwise in the problem). The 7 common strong acids are: HCl, HBr, HI, HNO3, HClO3, HClO4 and H2SO4 (1st proton only). How do...
The hydrolysis reaction was quenched by adding 10% perchloric acid (HClO4) and quenched reaction mixture was centrifuged to remove aggregated proteins. 5 ml of the quenched hydrolysis reaction supernatant were incubated with 995 ml of filtered malachite green solution (0.045% malachitegreen, 4.2% ...
Very recently we reported8 on the gas phase DEs of some superacids (HClO4, FSO3H, ClSO3H) applying the 6-31+G(d) basis set for calculating structures. Nevertheless, we are of the opinion now that the smaller valence basis sets also attain this objective, providing deviations from ...
The dried samples and crude cell wall extracts were digested in 3 mL of a mixed acid solution (HNO3-HClO4; v: v = 87: 13). The concentrations of Cu and Cd were determined with an Inductively Coupled Plasma Optical Emission Spectrometer (ICP-OES, PerkinElmer, Optima 8000, Waltham, MA, ...
Is HNO3 a stronger acid than HNO2? How often should you exfoliate with baking soda? Therefore, NO3 is more stable than NO2. So, we can proudly sayHNO2 is an Arrhenius acid.! Because HCl is completely dissociated in water, HCl is stronger than HClO4, resulting in more H-ions in an a...
