Witryna24 lis 2024 · Any acid that dissociates 100% into ions is called a strong acid. If it does not dissociate 100%, it is a weak acid. HC 2 H 3 O 2 is an example of a weak acid: HC2H3O2∼5% H + (aq) + C2H3O − 2 (aq) Because this reaction does not go 100% to completion, it is more appropriate to write it as a reversible reaction: HC2H3O2 ⇌ H + … Witryna6. What mass of phosphoric acid, H3PO4, would actually react with 7.17 grams of LiOH? 3LiOH + H3PO4 ® Li3PO4 + 3H2O; 7. 1. Given 0.400 mole of Li3PO4, a. how many Li3PO4 units are there? b. how many atoms of P are there?c. how many ions of lithium(Lit) are the? d. how many atoms oxygen are there? e. how many grams of … Witryna23 mar 2016 · 2. Just a guess- Lithium cation is smaller than the sodium cation, so the size of LiOH must be smaller than NaOH. Hence, the electrons will be pulled strongly, and it will be harder for them to … nsw doe teachers handbook leave
