3 Ways to Clean Your Toilet with Baking Soda Cleaning the toilet is probably the most irritating and tiring thing to do. The toilet is undoubtedly the filthiest part of our homes. You get fed up with scrubbing for hours and‚ in the end‚ you still feel that it isn’t clean enough. You experiment with many cleaning supplies but‚ none of them seem to work. Fortunately‚ we have the perfect solution to this problem. You can clean your toilet without wasting any time‚ money or energy. All you need are

bath salts‚ various fragrances‚ and other components. That said‚ there are a few key ingredients that most simple bath bomb recipes have: baking soda‚ citric acid‚ and cornstarch. When baking soda and citric acid are mixed together with some water‚ they undergo a chemical reaction. Specifically‚ this reaction involves acid-base chemistry‚ since the baking soda—also known as sodium bicarbonate (NaHCO3)—is a weak base‚ and citric acid (C6H8O7) is a weak acid. This reaction is shown in Equation 1‚ below

Baking. I have always enjoyed cooking and baking. My parents worked a lot of hours when I was a teenager‚ so dinner was left to me to cook. I soon learned all the usual family classics like spaghetti bolognaise‚ shepherds pie‚ roasts and cooked breakfasts. I became a lot more adventurous when I had my own family and quite often get the recipe books out to try something new. I only really got into baking once our boys came along and wanted to make them homemade cakes for their birthdays. I remember

History of Baking The History of Baking First Baking Course Ever Find Some Grain‚ a Mortar‚ and a Pestle Way back in the year 8‚000 B.C.‚ some clever dudes in Egypt started crushing grain with a mortar and pestle. You can bet they were surprised when after a few twists and grinds‚ a German chocolate cake appeared. Just kidding. They only managed to make a rudimentary form of unleavened bread sort of like a Mexican tortilla--but it was still a pretty big accomplishment. They shared this information

Objective Determine the concentration of acetic acid of vinegar‚ in terms of (m/m). Introduction Neutralization is a reaction of an acid with a bases to produce a salt and water. For example‚ the reaction of the strong acid HCl with the strong base NaOH produces the salt sodium chloride and water HCl(aq) NaOH(aq) ( NaCl(aq) H2O(l) Since the acid‚ base‚ and salt in this reaction are all strong electrolytes‚ the net ionic equation for this reaction is H(aq) OH-(aq) ( H2O(l) This same result

Titration Analysis of Vinegar Student: Araik Movessian Grade: 12 Course: SCH4U Teacher: Tijana Knezovic Purpose and Introduction: In this experiment the question of “what is the molar concentration of acetic acid in a sample of vinegar?” was answered via titration using a standard solution of sodium hydroxide‚ NaOH(aq). In this investigation‚ students are to act as quality control chemists. Their purpose is to test the acetic acid concentration of the vinegar to discover whether it

Bakery is still in business under the new management of the bakery by Mr. Nestor Agno. It was 1986 when Nestor Agno accepted the offer given by Elena Chavis to be the new administrator of the business. Mr. Agno attended some seminars regarding on baking different kinds of pastries and bread. After subsequent years‚ Mr. Nestor Agno decided to establish a new branch of Fatima’s Bakery that is located at 65 Justicia Street‚ Arty Subdivision Karuhatan‚ Valenzuela‚ City‚ and the responsibilities in operating

Determining the Molarity of Acetic Acid in Vinegar Abstract This experiment was done to determine the molarity of acetic acid in vinegar. The acetic acid in vinegar was titrated with a strong base sodium hydroxide to determine the equivalence point of this chemical reaction. The indicator phenolphthalein was used because the moment it changes color is on the basic side of the pH scale. To insure the experiment was done with the most accuracy‚ the two conductors of this experiment took three
