If 150mL of 0.10M NaOH is mixed with 50mL of 0.30M HCl, then the pH of the resultant solution is closest to? A. 7 B. 1 C. 13 D. 2 Thanks

Is the NH2 group a base? Thus, would the strength of aspirin as a base be less than the salicylic acid that made it (no other base sites changed) ?

Generally, the conjugate base of a weak acid is strong. NH4+ is considered a weak acid. Is its conjugate base NH3 therefore strong? I have some ideas about this but would like t …

Determine the pH of the final solution if 100.0ml of 2.000x 10^-3 M sulphuric acid is added to 40.0ml of 4.825x10^-3 M barium hydroxide.

Hey, ZnO(s) + 2HCl(aq) -> ZnCl2(aq) + H2O(l) What would be the conjugate pairs? Do we have to get rid of the Cl spectator ion in this case?

According to Heineman Chemistry Chapter 11: Organic Chemical Pathways: Biodiesel is a mix of esters produced by a chemical reaction between vegetable oil and an alcohol su …

I had a multiple choice question that asked: which one of the following chemical equations best represents the ionsation of the ethanoate ion CH3COO- I wrote the answer as the eth …

Do we have to know the specific indicator needed for reactions such as a) strong acid & weak base b) weak acid & strong base c) strong acid & strong base d) weak a …

I looked on wikipedia and the IUPAC name for citric acid is given as "2-hydroxypropane-1,2,3-tricarboxylic acid" But I thought that the longest carbon chain is 5, wouldn't you cou …

How would I write the balanced chemical equation for the reaction of aqueous hydrochloric acid with solid magnesium oxide? The reactants should be HCl(aq) + MgO(s) I first wrote …

Is the ionisation of acids in water, or even bases in water, endothermic or exothermic? eg. Is HCl + H2O ---> H3O+ + Cl- exothermic? Thanks
