Use the below data that i obtained from my lab and kindly with questions 2-5 and the observations/conclusion/interpretat ion of results .the aim of this experiment is to identify the defining characteristics of acids and bases, to define acidity and explain how the ph scale relates to the acidity of a substance, to distinguish between strong and weak acids in relationship to the acid ionization constant (ka), and to discuss the purpose of a ph titration curve and define the half-equivalence point and equivalence point. in so doing, we will perform ph analysis utilizing ph indicator strips, perform a titration of a weak acid against a strong base, construct an accurate titration curve using experimental results, and determine ka for an unknown weak acid utilizing the data collected during the experiment. resultsexperimental data (these can also be organized in a table or graph): calculations: experiment 1data table 1: determination of equivalence pointtrial 1trial 2volume of unknown weak acid 4 ml4 mltotal number of drops required to reach equivalence point 110110average number of drops 110data table 2: titration curve valuesdrops naoh added ph value trial 1 ph value trial 2 ph value (average)half-equivalent point equivalent point 11011011004441066620666306664066650 00777808889088810010101011010101012 0101010panel 1: equivalent point number of drops46 drops of naohpanel 2: half-equivalent point number of drops93 drops of naohdata table 3: determination of unknownpka of unknown weak acid: 6.0ka of unknown weak acid: 10-6unknown weak acid identity: carbonic acid (h2co3% error pka: 5.81%% error ka: 132.56%ph vs drop of naoh curve 12 r 10 0 0 20 40 60 80 100 120 140 drops of naohph indicator strips work by changing color in the presence of solutions with varied ph values. thinking about your procedure steps and results in part 1, why do you think the ph of the unknown weak acid was not determined with ph indicator strips until part 2? discuss possible causes of error in the experimental procedure. why do you think there was a percent of error in the pka and ka values of the unknown weak acid, in comparison to the values presented in table 2? do you think using a ph meter instead of ph indicator strips would have created a larger or smaller percent error? explain your answer.5. why was phenolphthalein a good indicator to use for determining the equivalence point between the unknown weak acid and strong base? observations and conclusions:
