You will titrate 25.00ml of histidine dihydrochloride solution of unknown concentration with the secondary standard naoh solution prepared in the last experiment. the unknown histidine dihydrochloride solutions have concentrations in the range 0.022-0.030m. use a value of 0.025m histidine dihydrochloride to estimate the volume of naoh required to completely deprotonate the histidine dihydrochloride. you will need to use the concentration of naoh from your last experiment. this calculated volume is an estimate of the third equivalence point. use this value to estimate the first and second equivalence point volumes.

h let me think

the number of protons in the nucleus of a given element. has slight luster and conducts electricity at high temperatures like metal.but like a nonmetal,boron is brittle and does not conduct electricity well at low temperatures. in graphite, carbon is a soft,brittle solid.it is reflective,ductile,or malleable.

answer:

the reaction is type of combination reaction.

explanation:

on the product side, there are 2 molecules of bonded to fe   which means one atom of fe are combined two molecules of . so, balanced chemical equation becomes :

this reaction follows the reaction type of combination reaction. a combination reaction is defined as chemical reaction in which reactants combines together to form a single product.
