Which is not effectively matched via its description?a. weak acid/partially ionizedb. salt/cation of an acid, anion of a basec. solid soluble base/soluble steel hydroxidedd. weak base/accepts H+ from an acide. solid electrolyte/solid acid, solid base, or soluble salt
which electrolyte is not effectively matched?a. KClO3/soluble saltb. HCN/weak basec. Ba(OH)2/strong soluble based. HNO3/ solid acide. (NH4)2SO4/soluble salt
If extra OH- isincluded to a sample of pure water, which of the following statements is incorrect?a. The equilibrium position shifts to the leftb. The solution becomes even more basicc. the H3O+ increasesd. The > e. the amount of the non=ionized H2O increases
Which of the following 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 incorrectly matched through 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 adhering to statements about measurement of pH is incorrect?a. the ph of a solution have the right to be figured out usage a ph meterb. the ph of a sultion have the right to be identified by the indicator methodc. a ph meter iseven more specific than an indicator for determing the phd. many signs are solid acids or strong basese. acid base signs have different colors in options of differents pH
which of the complying with statements about weak acids is false?a. weak acids ionize only slightly in diute aqueous solutionb. the Ka values for weak acids are numbers that are higher than 1c. weak acids are mych more countless than strong acidsd. many kind of weak acids are acquainted to us in daily uwatch. the ionization constatnt for a weak acid does not include a term for the concentration of water
which of the following statements about polyprotic acids is incorrect?a. polyprotic acids can furnish 2 or even more hydronium ions per moleculeb.it is mostly embraced exercise to ignore second or 3rd ionizations when caluclating the concentration of H3O+c. the ionizations of polyprotic acids occur simulataneouslyd. successice ionization constants for polyprotic acids generally decreaview. phosphoric acid is a typocal polyprotic acid
