The acid-base titration curves help to find the pKa‚ Ka‚ and pH at equivalent point. At the beginning pH for HCl is 1.90 which is lower than the 3.28 for acetic acid; thus‚ strong acid (HCl) means lower pH and weak acid (acetic acid) means higher pH. Then at the equivalent point for the titration HCl-NaOH the pH is 7‚ which mans that is neutral‚ in other words there are enough NaOH mmol to neutralize the HCl mmol present; also‚ the solution contains only water and NaCl the salt derived from the titration

Perspectives: Effects on Research and Writing Every person ’s perceptions are entirely inimitable in their own way. Perception‚ in itself‚ means to interpret the world around‚ in one ’s own way based on their personally acquired morals‚ values‚ and fears. Our minds begin to examine and interpret things using these traits. How does this all relate to research and writing? After making interpretations‚ a person then begins to form an opinion about the subject at hand. When writing‚ a topic is

I can see why people would use that stereotype on her. A lot of the people see using the well fare system are dead beats so to speak‚ people that are too lazy or on drugs to go find a decent job. With Carol Paik she keeps getting the Asian stereotype where people think she looks like other Asians. I also can understand

Anna Powell 2nd I.Title: Acid-Base Titrations AP Chemistry Laboratory #6 II.Purpose: The purpose of this experiment is to standardize a sodium hydroxide solution and use the standard solution to titrate an unknown solid acid. The equivalent mass of the solid acid will be determined from the volume of sodium hydroxide added at the equivalence point. The equilibrium constant‚ Ks‚ of the solid acid will be calculated from the titration curve obtained by plotting the pH of the solution versus

The term "adult citizens" refers to Filipino citizens of legal age who --- for one reason or another --- have had little or no formal education. The term "out-of-school youth" refers to children and young people of school age who cannot or have decided not to attend formal school due to some personal reasons.

accuracy of my senses can be on point when things are clear and there is nothing clouding my thinking‚ example when I have had a good day and there have been no distractions then things make sense. On the other hand the daily concerns which are presented in general may cause my sense to be altered therefore things that would make sense are distorted and challenged. Our sensual perception (using sight as an example) can deceive our brain in three major ways: limited biologically‚ we see the superficial;

Is homosexuality biological based? Homosexuality is biologically based. It’s not something someone gives a try and sees if they like it. Maybe the occurrences have something to do with the mother’s hormone levels when she is pregnant. I also think it is a little of both. Some cases it might be the X and Y thing and others it is probably just learned. I think most of the recent ones are probably learned because it is all over TV and everything. I just think it is ridiculous that they expect us
