The Effect of the Number of Drops of HCl and NaOH on the Net Change in the pH of Plant‚ Animal‚ and Nonbiological Solutions Research Question: How do plants and animals respond to changes in pH? Analysis Questions: Summarize the effects of HCl and NaOH on the tap water. HCl is an acid and when in tap water‚ dissociates into H+ and Cl-. Since it releases the H+ ion in the tap water‚ it raises the concentration of H+‚ which lowers the pH of the tap water. Unlike HCl‚ NaOH is a base. NaOH is a base because

Determination of NaHCO3 in Alka-Seltzer Introduction: Sodium Bicarbonate also referred to as baking soda‚ Bicarbonate of soda‚ Sodium hydrogen carbonate‚ and Carbonic Acid Monosodium salt‚ acts an ionic or salt compound when put in an aqueous solution. Its molecular weight is 84.006 g/mol and it is usually found in a dry powder form that is similar to slat. It is white‚ odorless‚ and has a melting point of 108.9 degrees Celsius. It has a density of 2.1 g/cm3. Sodium Bicarbonate is an electrolyte

that the change in HCl concentration does affect the rate of reaction with the Calcium carbonate pebbles. The relationship between the change in HCl and reaction rate can be seen in the graph and raw data table presented above. If you compare the lowest concentration with the highest concentration you’d be able to see that there is a very large contrast between their averages. The average gas production of 0.1M HCl was 0.00693 kPa/s whereas the average gas production for 1M HCl was 0.257. This clearly

Nicotine and Reaction Time Introduction: Nicotine is a drug‚ nerve poison‚ sedative and also a stimulant. It is said to have stimulating and relaxing effects‚ but it depends on the dosage of nicotine. As it was mentioned above‚ Nicotine is both a stimulant and a sedative; this means that straight after you have ingested nicotine‚ it gives you an adrenaline rush and also helps you to relax afterwards i.e. crash. This means that if I conduct my experiment straight after the smokers have ingested nicotine
