What is Alkaline Solutions Fill in the blank: H+ OH- Type of solution 1.0x 10 -3 ? ? H+ OH- Type of solution 1.0x 10 -3 1.0x 10 -11 acidic This particular case could not be an Arrhenius base. What is NH3 ammonia What is a proton acceptor? What is a base When an acid loses a hydrogen ion it becomes a... What is a base Fill in the blank: Conjugate base Some substances, such as water, are amphoteric, what is another name for amphoteric? What is amphiprotic Color indicators are organic compounds that establish equilibrium between their ________ form and ionic form in solution. What is molecular The pH at which the color change occurs is called the ? . What is the end point What type of indicator is this... What is phenolphthalein A solution is tested: methyl red= yellow and bromothymol blue = yellow. What is the concentration of the sample? What is six HCl is a strong acid. In an aqueous solution it will ionize % What is 100 H2SO4(aq) + HOH(l) H3O+(aq) +HSO4-(aq) How many ionisable hydrogen(s) does this equation contain What is two Find the percent ionization of 0.100M solution of formic acid if it’s [H +] = 4.22x10-3 M What is 4.22x10-3 x 100 = 4.22% 0.1 A 0.40 M solution of HClO3 is 0.027% ionized. Find the Ka for this acid. [H+] = 0.027 • (0.40) = 1.08 x 10-4 M 100 HClO3(aq) H+(aq) + ClO3-(aq) Ka = [H+][ClO3-] [HClO3] Ka = (1.08 x 10-4)(1.08 x 10-4) (0.3999) Ka = 2.9 x 10-8 Acids taste sour, bases taste What is bitter ? An unknown acid has a H+ of 3.9x10-3, what is the OH-? What is 2.6x10 -12 Find the pOH of a solution with a + -3 [H ] of 6.7x10 What is 11.8 Acid + Base What is salt + water Calculate the volume of seawater with a pH of 7.80 that contains 1.0 mol of hydroxide ions. pH = 7.8 = pOH = 6.2 = [OH-] = 6.3 x 10-7 M 6.3 x 10-7 mol = 1 L 1 mol = ?L = 1.58 x 106 L A is a technique for finding an unknown concentration of one chemical from the known concentration of a second chemical. What is titration Find the concentration of an HF solution if 15.0 mL of 0.200 M KOH just neutralized 20.0 mL of HF. HF + KOH → KF + H2O Step 1 Step 2 Step 3 n = MV = (0.200 mol / L)(0.0150 L) = 0.00300 mol KOH x mol HF = 0.00300 mol KOH x 1mol HF = 0.00300 mol HF 1 mol KOH M = n = (0.00300 mol) = 0.150 mol = 0.150 M V (0.0200 L) L A titration shows that 242 mL of 0.500 M NaOH will just neutralize all of the acetic acid that is present in 150.0 mL of vinegar. Find the % by mass of acetic acid in vinegar. NaOH + HC2H3O → NaC2H3O2 + H2O Step 1 n = MV = (0.500 mol) (0.242 L) = 0.121 mol NaOH L Step 2 x mol HC2H3O2 = 0.121 mol NaOH x 1 mol HC2H3O2 = 0.121 mol HC2H3O2 1 mol NaOH Step 3 x g HC2H3O2 = 0.121 mol HC2H3O2 x 60 g HC2H3O2 = 7.26 g HC2H3O2 1 mol HC2H3O2 Step 4 % mass = 7.26 g x 100 = 4.84% acid 150.0 g assumed
