Worksheet - Acids‚ Bases and Salts 1. I am pure water. When heated my pH (increases‚ decreases)‚ because more of my water molecules dissociate. 2. I am a 0.020 M solution of weak acid‚ HA. If I only dissociate to the extent of 1.50%‚ what is the value of my Ka? 3. I am a 0.20 M solution of hydrocyanic acid‚ HCN‚ with a Ka of 4.93 x 10¯ 10 . What is my pH? 4. I am a buffer made from 0.10 M acetic acid and 0.15 M sodium acetate. If the Ka for acetic acid is 1.77 x 10¯ 5 ‚ what is my pH? 5. I am

Saline Salt Company Analysis The Saline Salt Company production process was simple. Their process involved extracting salt from six tanks of 900‚000 cubic feet of seawater which could only be held on a large plot of land. As land becomes more valuable and rarer‚ expansion of the existing method becomes very difficult. Saline Salt Company could not compete with other companies that were producing larger amounts of salt in shorter amounts of time. Saline Salt Company did not expand as the needs

questions on the effects of salt on grass growth. In the winter‚ many people place a salt compound on their driveways to melt snow and ice that has accumulated. The following spring‚ it is noticed that the edges of the driveway does not have any grass growing and grass a little further from the driveway is growing slower than the rest of the lawn. It will be determined if grass growth is negatively impacted in the spring after a winter of salt compound applications. Salt and Grass Growth Introduction:

Katie Paez Marine Science Salt Marsh Essay Salt marshes play vital roles in coastal areas‚ such as Westhampton‚ Southampton‚ Hampton Bays‚ and many other locations. Let’s look at the global effects of salt marshes. A study from September of this year published in UVAToday shows that the carbon stored in salt marshes may help in slowing global climate change. Carbon dioxide is the predominant so-called “greenhouse gas” that acts as sort of an atmospheric blanket‚ trapping the Earth’s heat. Over

People have been using salt since 6050 bc.We have used it for seasoning‚ preservation‚ and in the last century for lowering the freezing point of water(History of Salt). In pure water 0 degrees celsius is the normal freezing point of water. Ice will melt just as fast the water will freeze. You won’t see the melting and freezing processes as long as they are balanced and equal. Adding salt or any foreign substance to the water upsets the fragile equality between freezing and melting.
