Studying the pH of Strong Acid‚ Weak Acid‚ Salt‚ and Buffer Solutions The purpose of the current experiment was to determine the pH of various hydrochloric acid and acetic acid solutions‚ to determine the pH of various salt solutions‚ to prepare a buffer solution‚ and determine the effects of adding a strong acid and strong base to the buffer solution versus adding a strong acid and strong base to water. The measured pHs for the hydrochloric acid solutions were 1.6‚ 2.2‚ 2.9‚ and 3.8. The measured

Aim To investigate the effects of increasing salinity on potato cell mass. Background Information This experiment is based upon osmosis. Osmosis can be defined as the net movement of water molecules from a region with high concentration to a region with low concentration. This movement must take place across a partially permeable membrane such as a cell wall‚ which lets smaller molecules such as water through but does not allow bigger molecules to pass through. This process will take place until

Investigating the Difference in Isotonic Point in Sweet and White Potato Research Aim: To observe whether equal sized white potato or sweet potato cores reached the isotonic point in the same concentration of sucrose solution. Introduction: Osmosis is diffusion of water from areas of high water potential to areas of low water potential. It does not require an input of energy. Plants use osmosis to transport minerals from their roots to their leaves‚ and to take in water in the soil. Because the

Comparisons between The Hispanic Migration to the United States & the Irish Potato Famine The Irish Potato Famine and The Hispanic Migration are completely different things that happened at 2 different times‚ but there are some things that are similar. The push and pull factors of these 2 migrations are the environmental‚ social‚ and political reasons. These reasons are very important when it comes to leaving or going to a new country or place. The environment of Mexico is very rough and very

vacuole of a potato cell. We will investigate how the mass of the potato chips change in different sucrose solution concentrations. We will use osmosis to do this. I will be measuring and controlling many different variables‚ these include; - The dependent Variable Weight of potato chip Independent Variable Concentration of sucrose Control Variables consist of; - 1. Temperature 2. Surface area of potato 3. Volume of sucrose solution 4. Same time for each potato chip submerged

and plants cells. In human bodies‚ the process of osmosis is primarily found in the kidneys‚ in the glomerulus. In plants‚ osmosis is carried out everywhere within the cells of the plant (World Book‚ 1997). This can be shown by an experiment with potato and glucose/salt solution. The experiment requires putting a piece (or more) of potatoes into glucose or salt solution to see the result of osmosis (a hypertonic type of solution is mostly used as it would give the most prominent visual prove of osmosis

Store-check Report I. Introduction Potato chips is the most popular and common snack for Filipinos‚ both children and adults. The objective of this study is to deliver to customers the different pricing trends of the producers of potato chips to its market. One of the leading brands that is fast-selling is Jack n’ Jill’s Piattos. This potato chip brand runs through the market in many countries including Thailand‚ Malaysia‚ China‚ Indonesia and Vietnam for 46 years (Source: http://www.universalrobina

I have been asked to investigate the effects of osmosis on potato cell sap. I will test potato cylinders in different strengths of sucrose solution and record any results in a table. I will then analyse my findings and work out the isotonic point of the potato cell sap. Prediction I have looked at my scientific knowledge from the background theory I carried out and I will base my prediction upon this information. In this experiment‚ I expect the different concentrations to show fairly noticeable

SUMMARY‚ COMCLUSSION AND RECOMMENDATION The main objective of the study was to develop sweet potato cookies. Specifically‚ it sought to (a) evaluate the sensory qualities of sweet potato cookies in terms of appearance‚ odor texture and taste. (b) determine the most suitable treatment based on general acceptability. (c) determine if there is a significant difference on the proximate composition between control and the most acceptable treatment in terms of moisture‚ ash‚ crude fat‚ and protein
