Sulfurous acid, H_2SO_3, is a diprotic acid with K_a1 = 1.3 times 10^-2 and K_a2 = 6.3 times 10^-8. The acid forms when sulphur dioxide (a gas with a suffocating odor) dissolves in water. a. What is the pH of a 0.25 ...
a. H2SO4 b. HI c. HBr d. HF e. HClO4 Acid Strength: Acids can be strong, in which they fully dissociate in water to make the same concentration of hydronium ions as the concentration of acid, or they can be weak and not fully dissociate, making a much smaller con...

a teacher is good at chemistry, this is no indication of their ability to teach you or your child. The dissociated molecules are in equilibrium with undissociated molecules. No matter how much water you remove, that will be true. What happens when you mix a strong acid and a strong base...
What is the concentration of H^+ in a solution of 0.02 M NaOH? What is the concentration of OH- in a solution that contains 0.225 g of NaOH in 0.250 L of solution? A 5.00 g quantity of a diprotic acid (H2A) was dissolved in water and made up to exactly 250 m...
5-Spirocyclopropane isoxazolidines can be selectively converted into azetidin-2-one derivatives by heating in the presence of a protic acid such as trifluoroacetic acid (TFA) or p-TsOH. The ring contraction with concomitant extrusion of ethylene appears to be a general process and can be ...
remaining ester is hydrolysed by a water molecule that is activated by the His51-Asp75 catalytic diad. During this two-stage reaction, the protein conformation is thought to change. It is likely that the DENV protease operates in a similar manner (see supplementary Fig. S2), with a ...
