The Senate approved the legislation earlier Wednesday in a 78-20 vote, and Obama signed it into law that evening. All 20 ânoâ votes in the Senate came from Republicans, though Sens. Marco Rubio (R-Fla.) and Lindsey Graham (R-S.C.), both running for president, missed the vote. Without action by Congress, the federal government would have shut down on Thursday, the beginning of a new fiscal year.
A buffer is made by mixing a large volume of a weak acid or weak base together with its conjugate. A weak acid and its conjugate base can remain in solution without neutralizing each other.
Therefore, to understand how these organs help control the pH of the blood, we must first discuss how buffers work in solution. Acid-base buffers confer resistance to a change in the pH of a solution when hydrogen ions (protons) or hydroxide ions are added or removed.An acid-base buffer typically consists of a weak acid, and its conjugate base (salt) (see Equations 2-4 in the blue box, below).herefore, to understand how these organs help control the pH of the blood, we must first discuss how buffers work in solution.
