the most bubbles? If baking powder‚ baking soda‚ and salt are added to different test tubes of sugar water‚ then baking soda will have the most effect on the rate of fermentation (create the most bubbles). This hypothesis is rejected. Based off of data‚ the hypothesis was rejected. The ingredient that produced the most bubbles was baking powder. In the experiment finishing at 20 min.‚ the control had 2.5 cm of bubbles produced‚ the salt produced 1.5 cm of bubbles‚ the baking soda produced 1.5 cm of

INTRODUCTION: Nowadys‚ indicators have become technologically advanced and can be used for the main purpose of indicating whether something is acidic‚ basic or neutral. This is possible because in solutions of different pH‚ the colour of the inidcator will change simultaneously with pH change. This is made possible by pigments in the indicators. Hand made indicators include universal indicator‚ methyl orange‚ phenolphthalein and many more. Acids and bases are diverse in this world. They are everywhere

release of an OH- (hydroxide) ion. When a hydrogen ion is released‚ the solution becomes acidic. When a hydroxide ion is released‚ the solution becomes basic. Those two special ions determine whether you are looking at an acid or a base. For example‚ vinegar is also called acetic acid. (Okay‚ that gives away the answer.) If you look at its atoms when it’s in water‚ you will see the molecule CH3COOH split into CH3COO- and H+. That hydrogen ion is the reason it is called an acid. Chemists use the word "dissociated"

see how the pill bug reacted with certain man made substances and two substances that they would find in their everyday habitat. We tested ketchup‚ orange juice‚ sand‚ baking soda‚ flour and water. The pill bugs did not like the ketchup and orange juice I believe because of the strong acidic smell and it didn’t like the baking soda because of the texture. The pill bugs didn’t have a problem with the water and sand because those two are found in the everyday life. The data that we found did not

Kendall ABSTRACT The purpose of this research was to study the science of mummification by mummifying a Hungarian sausage using baking soda. The researchers tried to mummify three Hungarian sausages in baking soda over a period of more or less than ten days. On the first day‚ the researchers placed a Hungarian sausage in an air-tight container of baking soda and put it in a drawer for more or less than a week after measuring its length‚ circumference‚ and weight. After that a week‚ the researchers
