Question 1 What are the listed hazards for 0.1N sodium hydroxide? Severe eye irritation. All of these options are correct. May cause severe gastrointestinal irritation. Skin irritation.

Each value represents a different aqueous solution at 25 °C. Classify each solution as acidic, basic, or neutral. Acidic pOH = 8.58 [H*] =3.4 x 10-2 pH = 8.24 [H+] = 5.4 x 10-12 pOH = 7.00 pH = 3.13 Basic Answer Bank [OH-] = 3.9 × 10-5 [OH-] = 1.3 x 10 Neutral [H]=1.0 x 10-7 pOH = 5.25

3. What is the pH in a solution with [H*]=2.5x10-5?

Calculate the pH of a 0.36M methylamine (weak base) (CH3NH2) solution, if Kb = 4.4x10-4   899 10 300 013 15

What is the conjugate base in this reaction: H,PO,+ H,O H,O+H,PO, O H.0+ O HO O HPO, O OH

In need of help with all parts please!

What is the [OH-] and pH of a 0.35 M solution of hydroxylamine (a weak base, NH3OH)? Kb = 1.10 x 10-8

Calculate [OH ], H*], and the pH of 0.37 M solutions of each of the following amines ( Kb for aniline is 3.8 х 10 10 K, for methylamine is 4.38 x 10-4). a. aniline [OH ]: M [H*] =( M pH b. methylamine = [_HO] |M [H*] =C |M pH

Calculate the OH concentration and pH of a 7.7 x 10-³ M aqueous solution of sodium cyanide, NaCN. Finally, calculate the CN concentration. ( K₂ (HCN) = 4.9 × 10-¹⁰) [OH-] M pH = [CN] = 3

A solution of vinegar corresponds to about 0.400 M. At this concentration, with Ka = 1.8 x10-5 , what is the pH of vinegar? Vinegar formula (CH₃COOH) Show the ICE table and your calculation to get to the pH value.
