  • Rubidium

    Rubidium is a very soft, silvery-white metal in the alkali metal group Rubidium metal shares similarities to potassium metal and caesium metal in physical appearance, softness and conductivity Rubidium cannot be stored under atmospheric oxygen, as a highly exothermic reaction will ensue, sometimes even resulting in the metal catching fire...

    A low urine pH itself cannot directly account for excretion of a significant amount of acid: for example, at the limiting urine pH of about 44, [H +] is a negligible 004 mmol/lThis is several orders of magnitude lower than H + accounted for by titratable acidity and ammonium excretion (ie 004 mmol/l is insignificant in a net renal acid excretion of 70 mmols or more per day)...
