What is the hydronium ion concentration in an aqueous hydrobromic acid solution with a pH of 4.230? 

[H3O+] = _________ M

[Review Topics]
[References]
Strong acids and strong bases ionize 100% in aqueous solution.
HCl is a strong acid. In solution we write it as H (aq) + C (aq).
HF is a weak acid. In solution we write it as HF(aq).
KOH is a strong base. In solution we write it as K(ag) + OH (ag).
NH, is a weak base. In solution we write it as NH3(aq).
Exception: Since Ca(OH)2 is only slightly soluble we write it as Ca(OH)2(s).
Below is a list of the 6 strong acids and 6 strong bases you should know. All other acids and bases are considered weak.
Strong Acids
HCI, HBr, HI
HNO3
Strong Bases
LiOH, NaOH, КОН
Ca(OH)2 (slightly soluble)
HCIO4
Ba(ОН)2
H,SO4
Sr(OH)2
