CHAPTER I INTRODUCTION Researchers focused much of their attention in studying the importance of the effect of using pH in germination of seeds, because of the thought that if the seeds wil grow fast in using the pH. BACKGROUND OF THE STUDY The researchers chose this study because they want to know wha t will happen if they use pH in germination of seeds. The researchers wanted to study the effect of using the pH in germination of seeds, because they want to kow if their research will be effective. STATE OF THE PROBLEM MAIN PROBLEM What is the effect of using pH in germination of seeds? SUB PROBLEM 1.Will affect the germination of seeds by using of pH? 2.Can affect the germination of seeds by using of pH? 3.It affect the germination of the seeds by using pf pH MAIN OBJECTIVES To determine the effect of pH in germination of seeds. SPECIFIC OBJECTIVES 1.To know the effect of pH in germination of seeds. 2.To answer the effect of pH in germination of seeds. 3.To explain the effect of pH in germination of seeds. SIGNIFICANCE OF THE STUDY The study focused on explaining the effect of pH in germination of seeds. More over, the results of the study will be beneficial to the following: The researchers will have an awarness on the importance of the effect of pH in germination of seeds. CHAPTER II REVIEW OF RELATED LITERATURE In chemistry, pH is a measure of the acidity or basicity of an aqueous solution. Solutions with a pH less than 7 are said to be acidic and solution with a pH greater than 7 are basic or alkaline. Pure water has a pH very close to 7. The concept of p[H] was first introduced by Danish chemist Søren Peder Lauritz Sørensen at the Carlsberg Laboratory in 1909 and revised to the modern pH in 1924 to accommodate definitions and measurements in terms of electrochemical cells. In the first papers, the notation had the "H" as a subscript to the lowercase "p", as so: pH. The exact meaning of the "p" in "pH" is disputed, but according to the Carlsberg Foundation pH stands for "power of hydrogen". It has also been suggested that the "p" stands for the German Potenz(meaning "power"), others refer to French puissance (also meaning "power", based on the fact that the Carlsberg Laboratory was French-speaking). Another suggestion is that the "p" stands for the Latin terms pondus hydrogenii, potentia hydrogenii, or potential hydrogen. It is also suggested that Sørensen used the letters "p" and "q" (commonly paired letters in mathematics) simply to label the test solution (p) and the reference solution (q). Current usage in chemistry is that p stands for "decimal cologarithm of", as also in the term pKa, used for acid dissociation constants. The pH of different cellular compartments, body fluids, and organs is usually tightly regulated in a process called acid-base homeostasis. The most common disorder in acid-base homeostasis is acidosis, which means an acid overload in the body, generally defined by pH falling below 7.35.* Alkalosis is the opposite condition, with blood pH being excessively high. The pH of blood is usually slightly basic with a value of pH 7.365. This value is often referred to as physiological pH in biology and medicine. Plaque can create a local acidic environment that can result intooth decay by demineralization. Enzymes and other proteins have an optimum pH range and can become inactivated or denatured outside this range. CHAPTER III METHODOLOGY MATERIALS: PH POT SOIL SEEDS PROCEDURE: The first to do is prepare all the materials, after preparing all the materials, the second is put a soil in a pot and put the seeds in a soil and lastly watered the seeds by pH.
