Sodium thiopental

electrolysis of (KOH). The scientist used the same method to isolate sodium. KCI is the mineral that potassium can be obtained from. Caustic potash is a vital source of potassium that can be obtained in Germany, New Mexico, California, and Utah. Potassium is classified as a soft, waxy metal. If it is combined with oxygen it forms potassium superoxide and with water to form potassium hydroxide. If potassium is formed with sodium it can be used as a medium heat transfer. Davy’s experiments led him…

To start this laboratory experiment, we first collected all the materials necessary including multiple beakers, samples of each solution, metal strips, a salt bridge, alligator clips, and an abrasive sponge. Then 10 mL of CuSO4(aq) and 10 mL of ZnSO4(aq) were placed into separate 250 mL beakers. A copper strip was then placed in the beaker containing CuSO4(aq) and a zinc strip was placed into the beaker with ZnSO4(aq). The two beakers were connected by a salt bridge that consisted of a string…

Paracrine Signaling Signals that act locally between cells that are close together are called paracrine signals. Paracrine signals move by diffusion through the extracellular matrix. These types of signals usually elicit quick responses that last only a short amount of time. In order to keep the response localized, paracrine ligand molecules are normally quickly degraded by enzymes or removed by neighboring cells. Removing the signals will reestablish the concentration gradient for the signal,…

potential of Neuron A (presynaptic neuron) reaches -60mV the sodium and potassium channels in the neuron open at the beginning of the axon. The influx of positive sodium ions into the cell makes the inside of the cell more positive and leaves the outside of the cell more negative. The cell is at rest at -70mV and as it gets more positive, it reaches threshold (gets more excited). This change in electrical potential also excites neighboring sodium and potassium channels to open up in a chain…

It is well known that all organisms require at least some water to survive, even the most hardy creature on the planet earth, the tardigrade, Hypsibius dujardini, which can survive near complete dehydration, exposure to extreme radiation, vacuum, temperature and pressure, must be rejuvenated with water if it is to resume life after near complete desiccation (Gabriel, et al. 2007). H. dujardini, famous for surviving some of the harshest conditions of any organism we know of, is a perfect example…

1. Observation. - Compound X is a white powder. It is a solid. 2. Questions. - What is compound X? - What will happen when compound X is heated and reacted with C20H14O4 (phenolphthalein – an acid-base indicator)? (1) - How does compound X react with C20H14O4 (phenolphthalein)? (2) - How does compound X react with water? (3) - How does compound X react with hydro chloric acid (HCL)? (4) 3. Predictions. - Compound X is calcium carbonate (CaCO3). - (1) When compound X is heated and reacted with…

oxide that works as both an acid or a base. Thus, the reaction resulted in the production of a murky coloured liquid. If a full neutralization reaction was to completed, a product of a transparent solution should have been created. Sodium phosphate and potassium sodium tartrate are both not strong bases and that is why the average pH change was quite low. Both of them are not bases, however, they have a high pH. This is why they were both able to increase the pH on the acidic solution. A…

The rate at which a reaction occurs, referred to as reaction rate, is a type of reaction property that directly measures the extent of a reaction. Changes in concentration affect reaction rates in chemical formulas, and if the reaction is not specifically known, the rate cannot be determined. The rates are given in negative or positive measurements depending on whether the concentration is a reactant or product. Knowing this, the first step in finding the reaction rate would be to determine the…

Research Question: To compare the enthalpy change of reaction of 3 neutralization reactions by using 3 different acids of distinct pH. The same base of NaOH will be used in all three experiments. Introduction: Chemical reactions always have energy change. Energy in the form of heat, if liberated is known as exothermic and if absorbed in the reaction is known as endothermic. When a reaction carried out under standard condition at a of temperature 298K and 1 atm of pressure and 1 mole of water…
