You are watching: Which of the following is true about weak acids?

Which salt is created from a solid acid and a strong base?a. LiFb. KBrOc. NH4No3d. NaHCO3e. NaHSo4
Which is not correctly matched through its description?a. weak acid/partly ionizedb. salt/cation of an acid, anion of a basec. solid soluble base/soluble metal hydroxidedd. weak base/accepts H+ from an acide. strong electrolyte/solid acid, solid base, or soluble salt
which electrolyte is not properly matched?a. KClO3/soluble saltb. HCN/weak basec. Ba(OH)2/solid soluble based. HNO3/ solid acide. (NH4)2SO4/soluble salt
If additional OH- isadded to a sample of pure water, which of the complying with statements is incorrect?a. The equilibrium place shifts to the leftb. The solution becomes more basicc. the H3O+ increasesd. The > e. the amount of the non=ionized H2O increases
Which of the complying with relationships is incorrect? a. pH+pOH= 14b. =10^pOHc. pKw=-logKwd. =1 x 10^-14e. pH=-log
a solution having a pH of 1.4 would be defined as______.a. distinctly basicb. slightly basicc. neutrald. slightly acidice. distrinctly acidic
which pH or pOH is erroneously matched via its description?a. pH=1.32-distinctly acidicb. pOH= 13.8- disctinctly basicc. pOH= 7.8- slightly acidicd. pH=12.5 distinctly basice. pH= 6.7- slightly acidic
Which of the complying with statements around measurement of pH is incorrect?a. the ph of a solution can be established use a ph meterb. the ph of a sultion have the right to be determined by the indicator methodc. a ph meter ismore specific than an indicator for determing the phd. many type of indications are strong acids or solid basese. acid base indications have different colors in options of diffeleas pH
which of the adhering to statements about weak acids is false?a. weak acids ionize only slightly in diute aqueous solutionb. the Ka worths for weak acids are numbers that are better than 1c. weak acids are mych even more many than solid acidsd. many weak acids are acquainted to us in daily uwatch. the ionization constatnt for a weak acid does not incorporate a term for the concentration of water
which of the adhering to statements about polyprotic acids is incorrect?a. polyprotic acids can furnish 2 or even more hydronium ions per moleculeb.it is generally embraced practice to disregard second or third ionizations when caluclating the concentration of H3O+c. the ionizations of polyprotic acids happen simulataneouslyd. successice ionization constants for polyprotic acids mostly decreaview. phosphoric acid is a typocal polyprotic acid
