Acid-Base QuizletArrhenius Acid-Base Theory - correct answer Arrhenius defined acids and bases by what ions they dissociate into when dissolved in water. An Arrhenius acid dissociates into H+ ions and an anion when dissolved in water. An Arrhenius base dissociates into OH- ions and a cation when dissolved in water. Bronsted-Lowry Acid-Base Theory - correct answer Bronsted and Lowry defined acids and bases depending on whether they donated or accepted H+ ions (protons). This may happen in a...

What are the Bronsted-Lowry definitions of acid and base? Acids donate H+ and Bases accept H+ (BAAD) What is the difference between a strong acid and a weak acid? Give examples of each. Strong acids completely dissociate into anion and H+. Weak acids do not dissociate completely into anion and H+, they form an equilibrium system and reform acid and anion and H+ continuously. Strong acid ex. HCl and H2SO4 Weak acid ex. H3PO4 and HC2H3O2 What is the difference between a strong ...

MCAT Exam Practice Questions With Answers Latest Updated 2024 (100% Verified) Thin layer chromatography can use silica plates which are very polar. Will polar or non polar substances have lower Rf values on this plate? Polar substances - they will have a higher affinity for the silica and thus will not travel as far as the non polar substances A titration of a strong acid with a strong base or vice versa has an equivalence point around what pH? 7 What type of bond is usually disrupted duri...

What are the 5 steps in the Scientific Method? - Answer 1. Identify a problem or pose a question based on an observation. 2. Formulate a hypotheses. 3. Conduct experiments or tests the hypotheses. 4. Observe and record the results. 5. Draw a conclusion (was the hypothesis correct?). * peer review is also important.
