Is NaOH an acid, base, or salt? What is the pH of an aqueous solution of 3.92 x 10^{-2} M NaOH? Consider the titration of a 60.0 mL of 0.361 M weak acid HA (Ka = 4.2 x 10^-5) with 0.400 M KOH. After 30.0 mL of KOH has been added, what would the pH of the solution...
How many mL of the NaOH solution is needed to reach the equivalence point? If 25.31 mL of a 0.0500 M NaOH solution is required to reach the equivalence point of an acid-base titration of 40.0 mL of 7-Up, how many moles of citric acid are in ...
Acid-base Buffer Solutions: Dissolution of a weak acid and the conjugate base of that weak acid into the same solution will produce a buffer. The useful property of buffers is that they are able to maintain a given pH even if strong ...

H2CO3, strong acid Is NaOH classified as a weak or strong acid or base? Explain. Which of these acids is a component in vinegar? a) H2SO4 b) HCl c) HNO3 d) NaOH e) CH3COOH Classify NaOH as one of the following. a. weak acid b. weak base ...
1. When sulfur dioxide is dissolved in water, it forms sulfurous acid (H2SO3). 2. Sulfur dioxide is a weak acid, so it only partially dissociates in water. 3. Sodium hydroxide is a strong base, so it completely dissociates in water, forming sodium ions (Na+) and hydroxide ions (OH-...
