- What is the pH of a 0.000000220 M KOH solution at 25oC? Answer to three significant figures.arrow_forwardWhich of the compounds below is a base? Key Concept: Know the difference between an acid and a base. The Arrhenius definition of an acid is a substance that donates an H + when dissolved in H 2O while a base is defined as a substance that produces OH - ions when dissolved in water. A H3PO4 B HI C HF D Ca(OH)2arrow_forwardWhich of the following are polyprotic acids? Select all that apply Group of answer choices H3PO3 H2SO3 HCN H2Se HBrOarrow_forward
- Statement 1: Water can donate or accept proton depending on the reaction. Statement 2: By virtue of the chemical structure of water, it is said to have the capability to produce ionization reactions similar to what acids and bases can do where in the two statements is correct, and which is incorrect?arrow_forwardFor this question homework I had to write it in notebook and explain the wrong why it is and right why it’s right. So the first explains s given solution of 0.0001 moles of hydroxyl ions [OH-] per liter. What is the pH of this solution and I put (10-^4 - log [H+ ] - log 10 - ^4 and I said it was acidic but I think the correct is basic? Not sure I have to explain why it’s wrong why it’s right or find the correct The molecular formula for glucose is C6H12O6, what would be the molecular formula for an oligomer made by linking ten glucose molecules together? (Glucose) That’s incorrect because I just said glucose instead of what was the actual molecular formula for oligomer I have to figure out what can be correct for this Polymers of polysaccharides and proteins are all synthesized from monomers by a process called ____(synthesis of macro molecules) what happens during the process? (They are produced by chemical reactions and they are in four major classes of macromolecules)…arrow_forwardTech Please don't provide the handwriting solution if the pH of a 0.29 M aqueous solution of a weak base is 9.9, estimate the Kb of the base. Kb=?arrow_forward
