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.
For an individual weak acid or weak base component, see Buffering agent. For uses not related to acid-base chemistry, see Buffer (disambiguation). A buffer solution (more precisely, pH buffer or hydrogen ion buffer) is an aqueous solution consisting of a mixture of a weak acid and its conjugate base, or vice versa.uffer capacity for a 0.1 M solution of an acid with pK a of 7. Buffer capacity, Î², is a quantitative measure of the resistance of a buffer solution to pH change on addition of hydroxide ions. It can be defined as follows.
