A hydrogen and a hydroxide ion can also join together to form a water molecule. In pure water, hydrogen and hydroxide ions are present in a 1:1 ratio since the only source of these ions is the ionization of water. Acids and bases are substances which change the balance of hydrogen and hydroxide ions in water. In this lesson, we will first explore the chemistry of acids and bases, then we will show how to calculate their concentration mathematically.

18 Oct 2016. Medrol Dosepak (methylprednisolone) has a medium half life range of 18 to 36 hours - meaning it takes the body 18 to 36 hours to clear 50% of the drug from your plasma. For a drug to be totally eliminated from your system it takes around 5.5 times the half life. As an estimate then, after taking a single dose of methylprednisolone it should be out of your system after 8 days. (5.5 x 36 hours = 198 hours or just over 8 days) Other factors to consider: 1. How much and how often you have taken the drug. 2. Your metabolic rate â a slower metabolism will increase the time a drug remains in your system. 3.
