Determine whether the following hydroxide ion concentrations ([oh−]) correspond to acidic, basic, or neutral solutions by estimating their corresponding hydronium ion concentrations ([h3o+] using the ion product constant of water (kw).hydronium ion concentration [h3o+] solution conditiongreater than 1×10−7 m acidicequal to 1×10−7 m neutralless than 1×10−7 m basicit may to keep the following equation in mind as you workkw = [h3o+][oh−] = [1×10−7 m][1×10−7 m] = 1×10−14 m

Answer asap need to be answered by wednesday morning explain how a buffer works, using an ethanoic acid / sodium ethanoate system including how the system resists changes in ph upon addition of a small amount of base and upon addition of a small amount of acid respectively. include the following calculations in your i. calculate the ph of a solution made by mixing 25cm3 0.1m ch3cooh and 40cm3 0.1m ch3coo-na+. [ka = 1.74 x 10-5 m] ii. calculate the ph following the addition of a 10cm3 portion of 0.08 m naoh to 500cm3 of this buffer solution. iii. calculate the ph following the addition of a 10cm3 portion of 0.08 m hcl to 200cm3 of the original buffer solution.
