Question

Rank the following 0.10 M solutions in order of increasing pH. (Use the appropriate <, =, or > symbol to separate substances in the list.)

RbNO₃, RbOBr, HOBr, RbOH, HONH₃NO₃, HNO₃, HONH₂

Answer 1

Answer #1

increasing order of pH

HNO₃ < HOBr < HONH₃NO₃ < RbNO₃ < RbOBr < HONH₂ < RbOH

Explanation :

HNO3 is strong acid . so has lowest pH

RbOH os strong base . so it has highest pH

RbNO3 is the salt of strong base and strong acid .so pH = 7

HOBr is weak acid . so pH greater than HNO3

NH2OH is weak base .so pH less than RbOH
