You are watching: Which of the following is a weak acid?
Which salt is produced from a solid acid and a solid base?a. LiFb. KBrOc. NH4No3d. NaHCO3e. NaHSo4
Which is not correctly matched v its description?a. Weak acid/partially ionizedb. Salt/cation of one acid, anion that a basec. Solid soluble base/soluble metal hydroxidedd. Weak base/accepts H+ from an acide. Solid electrolyte/strong acid, solid base, or soluble salt
which electrolyte is not properly matched?a. KClO3/soluble saltb. HCN/weak basec. Ba(OH)2/strong dissolve based. HNO3/ solid acide. (NH4)2SO4/soluble salt
If added OH- isadded to a sample of pure water, i m sorry of the complying with statements is incorrect?a. The equilibrium place shifts come the leftb. The equipment becomes an ext basicc. The H3O+ increasesd. The
Which of the complying with relationships is incorrect? a. PH+pOH= 14b.
a solution having actually a pH that 1.4 would certainly be explained as______.a. Distinctly basicb. Contempt basicc. Neutrald. Contempt acidice. Distrinctly acidic
which pH or pOH is erroneously matched through its description?a. PH=1.32-distinctly acidicb. POH= 13.8- disctinctly basicc. POH= 7.8- contempt acidicd. PH=12.5 distinctly basice. PH= 6.7- contempt acidic
Which the the following statements about measurement of pH is incorrect?a. The ph the a solution can be figured out use a ph meterb. The ph that a sultion can be established by the indicator methodc. A ph meter ismore specific than one indicator for determing the phd. Numerous indicators are solid acids or strong basese. Acid base indications have various colors in services of differents pH
which of the following statements around weak mountain is false?a. Weak mountain ionize only slightly in diute aqueous solutionb. The Ka values for weak acids room numbers the are higher than 1c. Weak acids are mych much more numerous than solid acidsd. Numerous weak mountain are familiar to united state in everyday usee. The ionization constatnt because that a weak acid does not incorporate a term for the concentration of water
which that the adhering to statements about polyprotic mountain is incorrect?a. Polyprotic acids have the right to furnish 2 or much more hydronium ion per moleculeb.it is generally accepted practice come ignore 2nd or 3rd ionizations when caluclating the concentration of H3O+c.
