Answer:

B. NaBr

D. KOH

Step-by-step explanation:

Below is the solubility rules given for you knowledge.

Salts of

  • Group 1 elements are soluble(
    Li^+, Na^+, K^+,Cs^+, Rb^+)
  • Ammonium ion is soluble (
    NH4^+)
  • The nitrate are generally soluble(
    NO3^-)
  • of Cl- , Br- , and I- are soluble, except Ag+ , Pb+2, and (Hg2)+2
  • most sulfate are soluble, except Ba+2, Ca+2,Pb+2, Ag+, Sr+2.
  • most hydroxide salts are only slightly soluble, except NH+4, Li+, Na+, K+
  • Most carbonates are insoluble (CO3 2-) Except group 1 and NH+4
  • most phosphate are insoluble except group 1 and NH+4

so using the rules above

NaBr , KOH are soluble, Pb(OH)2 is slightly soluble and AgCl is not soluble.
