Which one of the following salts in insoluble in water?a. CrCl3b. AgFc. PbSO4d. Mn(NO3)2e. Cu(ClO4)2


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

Which salt is produced from a solid acid and also a strong base?a. LiFb. KBrOc. NH4No3d. NaHCO3e. NaHSo4
Which is not effectively matched through its description?a. weak acid/partly ionizedb. salt/cation of an acid, anion of a basec. strong soluble base/soluble metal hydroxidedd. weak base/accepts H+ from an acide. strong electrolyte/strong acid, strong base, or soluble salt
which electrolyte is not appropriately matched?a. KClO3/soluble saltb. HCN/weak basec. Ba(OH)2/solid soluble based. HNO3/ solid acide. (NH4)2SO4/soluble salt
If extra OH- isadded to a sample of pure water, which of the complying with statements is incorrect?a. The equilibrium position 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 following relationships is incorrect? a. pH+pOH= 14b. =10^pOHc. pKw=-logKwd. =1 x 10^-14e. pH=-log
a solution having actually a pH of 1.4 would certainly be defined as______.a. distinctly basicb. slightly basicc. neutrald. slightly acidice. distrinctly acidic
which pH or pOH is incorrectly 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 adhering to statements about measurement of pH is incorrect?a. the ph of a solution deserve to be established use a ph meterb. the ph of a sultion have the right to be established by the indicator methodc. a ph meter iseven more accurate than an indicator for determing the phd. many type of indicators are solid acids or solid basese. acid base indicators have various colors in options of diffeleas pH
which of the complying with statements around 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 even more numerous than strong acidsd. many kind of weak acids are acquainted to us in everyday uview. the ionization constatnt for a weak acid does not include a term for the concentration of water
which of the complying with statements around polyprotic acids is incorrect?a. polyprotic acids deserve to furnish 2 or more hydronium ions per moleculeb.it is generally welcomed practice to neglect second or third ionizations as soon as caluclating the concentration of H3O+c. the ionizations of polyprotic acids take place simulataneouslyd. successice ionization constants for polyprotic acids mainly decreawatch. phosphoric acid is a typocal polyprotic acid
