Free Essays on Welfare Mothers

In the article â€Å"Incarcerated Mothers† a lot of valid points and strong arguments are made. We learn in the beginning of the article that majority of the women in prison are mothers, and their needs are often neglected. Women’s healthcare needs and services are often ignored compared to male inmates. Majority of women mothers take care of themselves and abide by the rules simply to get out of prison as soon as possible so that they can see their children. Would it be a different case if we were discussing fatherhood? Yes, I think it would. For instance, incarcerated males receive many of the necessary services, such as, medical, dental, recreational, vocational, and educational services. However, does the male population of inmates deserve to have these benefits? I think that the men take advantage of these benefits. I do not think the main thing on their mind is getting out of prison to see their children. Many of them may not even know they have kids, they may be in jail for sexual abuse and therefore not care about their offspring. For instance, on page 262 the given quote is saying that men get in trouble for more harsh things, they try to escape, they don’t wear the proper clothes that they are supposed to, they get in fights with one another, and are rowdy compared to the women who abide by the rules and are quite so that they can go home and see their families. Clearly, if men are acting in such a manner then they are not concerned about acting properly in prison so that they can get out and get back to their families. Fathers in prison don’t necessarily have to prove themselves worthy of fatherhood, they don’t have to prove competency. Where as mothers have to prove this without expecting support for their mothering role. It is terrible to see that men don’t have to work as hard to get out to see their children. Both genders should have to equally prove themselves worthy of being a parent rather than t...

pH, pKa, and the Henderson-Hasselbalch Equation

pH, pKa, and the Henderson-Hasselbalch Equation The  pH  is  a measure of the concentration of hydrogen ions in an aqueous solution. pKa (acid dissociation constant) is related, but more specific, in that it helps you predict what a molecule will do at a specific pH. Essentially, pKa tells you what the pH needs to be in order for a chemical species to donate or accept a proton. The  Henderson-Hasselbalch equation describes the relationship between pH and pKa. pH and pKa Once you have pH or pKa values, you know certain things about a solution and how it compares with other solutions: The lower the pH, the higher the concentration of hydrogen ions, [H]. The lower the pKa, the stronger the acid and the greater its ability to donate protons.pH depends on the concentration of the solution. This is important because it means a weak acid could actually have a lower pH than a diluted strong acid. For example, concentrated vinegar (acetic acid, which is a weak acid) could have a lower pH than a dilute solution of hydrochloric acid (a strong acid). On the other hand, the pKa value is a constant for each type of molecule. It is unaffected by concentration.Even a chemical ordinarily considered a base can have a pKa value because the terms acids and bases simply refer to whether a species will give up protons (acid) or remove them (base). For example, if you have a base Y with a pKa of 13, it will accept protons and form YH, but when the pH exceeds 13, YH will be deprotonated and become Y. Because Y removes protons at a pH greater than the pH of neutral water (7), it is cons idered a base. Relating pH and pKa With the Henderson-Hasselbalch Equation If you know either pH or pKa you can solve for the other value using an approximation called the Henderson-Hasselbalch equation: pH pKa   log ([conjugate base]/[weak acid])pH pkalog ([A-]/[HA]) pH is the sum of the pKa value and the log of the concentration of the conjugate base divided by the concentration of the weak acid. At half the equivalence point: pH pKa Its worth noting sometimes this equation is written for the Ka value rather than pKa, so you should know the relationship:   pKa -logKa Assumptions That Are Made for the Henderson-Hasselbalch Equation The reason the Henderson-Hasselbalch equation is an approximation is because it takes water chemistry out of the equation. This works when water is the solvent and is present in a very large proportion to the [H] and acid/conjugate base. You shouldnt try to apply the approximation for concentrated solutions. Use the approximation only when the following conditions are met: −1  Ã‚  log ([A−]/[HA])  Ã‚  1Molarity of buffers should be 100x greater than that of the acid ionization constant Ka.Only use strong acids or strong bases if the pKa values fall between 5 and 9. Example pKa and pH Problem Find [H] for a solution of 0.225 M NaNO2 and 1.0 M HNO2. The Ka value (from a table) of HNO2 is 5.6 x 10-4. pKa  Ã‚  Ã¢Ë†â€™log  Ka  Ã‚  Ã¢Ë†â€™log(7.4Ãâ€"10−4)  Ã‚  3.14 pH pka log ([A-]/[HA]) pH  Ã‚  pKa  Ã‚  log([NO2-]/[HNO2]) pH  Ã‚  3.14  Ã‚  log(1/0.225) pH  Ã‚  3.14  Ã‚  0.648  Ã‚  3.788 [H]  Ã‚  10−pH  Ã‚  10−3.788  Ã‚  1.6Ãâ€"10−4 pH, pKa, and Henderson-Hasselbalch Equation Key Takeaways The pka is the pH value at which a chemical species will accept or donate a proton.The lower the pKa, the stronger the acid and the greater the ability to donate a proton in aqueous solution.The Henderson-Hasselbalch equation relates pKa and pH. However, it is only an approximation and should not be used for concentrated solutions or for extremely low pH acids or high pH bases. Sources de Levie, Robert. (2003).
