WebDec 30, 2024 · A titration curve is a plot of the concentration of the analyte at a given point in the experiment (usually pH in an acid-base titration) vs. the volume of the titrant added.This curve tells us whether we are dealing with a weak or strong acid/base for an acid-base titration. The curve around the equivalence point will be relatively steep and smooth when …

WebA solution of rubidium hydroxide is prepared by dissolving 1.546g of RbOH in water to make up 0.500L of solution. The molar mass of RbOH is 102.475gmol−1. What is the pH of the solution at 25.0∘C? Round the answer to three significant figures. WebJul 9, 2014 · pH = -log [H+] This means you take the negative log of the hydrogen ion concentration to find the pH. The hydrogen ion concentration is the same as the concentration of the acid because HCl is a strong acid and dissociates as follows: HCl -> H + + Cl− (notice the 1:1 ratio of HCl and H +) A 1M HCl solution has a pH of 0
WebOct 18, 2011 · RbOH, NH3 and Ca(OH)2. RbOH is the highest OH, followed by Ca(OH)2 and NH3. I rank RbOH higher than Ca(OH)2 because Ca(OH)2 isn't a soluble as RbOH. acid: HBr, HF HBr is a strong acid; HF is a weak acid. You should be able to rank all of them now. WebAug 7, 2010 · Since it is a strong base that gives one hydroxide ion per formula unit, the pH of an RbOH solution is equal to 14 + the logarithm of the molar concentration. So a 1.0M solution has a pH of 14, a...
