CO32- + 2H+ + 2Cl- → 2Na+ + 2Cl- + H2O + CO2 CO32- + 2H+ → H2O(l) + CO2(g) With this reaction the carbonate and the diatomic hydrogen combined together to make the bubbling effect that we had noted. This leaves us with the water molecule with the sodium chloride dissolved in it with the carbon dioxide gas bubbles. 4. NaOH(aq) + HCl(aq) → NaCl(aq) + H2O(l) Na+ + OH- + H+ + Cl- → Na+ + Cl- + H2O(l) OH- + H+ → H2O This reaction with a strong acid‚ as noted‚ released heat‚ which we call an exothermic

present in commercial bleach. Introduction Many commercial products‚ such as bleaches and hair coloring agents‚ contain oxidizing agents. The most common oxidizing agent in bleaches is sodium hypochlorite‚ NaClO (sometimes written NaOCl). Commercial bleaches are made by bubbling chlorine gas into a sodium hydroxide solution. Some of the chlorine is oxidized to the hypochlorite ion‚ ClO-‚ and some is reduced to the chloride ion‚ Cl-. The solution remains strongly basic. The chemical equation

Results and discussion: I. a. How would you compare that relative reactivity of Na and k -Sodium and potassium react somewhat similar when reacting with water however they are slightly different. Sodium moves because of the hydrogen coming off of it and has a low melting point while potassium’s reaction is faster and enough heat is produced to set light to the hydrogen coming off of it. Each leaves a pink color hue in the water. Discuss the similarities and differences in the behavior of the metals

acidosis? What is this called? What effects does it have? 3. Burn patients have damaged skin cells that are unable to prevent water loss. The kidneys help retain water by using the sodium-potassium pump. It pumps more sodium into the cells so that water can follow the movement of sodium and can be reabsorbed. Sodium ions are exchanged with potassium being pumped out of the cells into the renal tubules‚ where it’s secreted in urine. Therefore‚ potassium levels in urine are high. 4. Acidosis can

HYPERNATREMIA) AND SODIUM BALANCE (HYPOVOLEMIA AND EDEMA) Literature review current through: Sep 2013. | This topic last updated: ene 15‚ 2013. 1. INTRODUCTION — The plasma sodium concentration is regulated by changes in water intake and excretion‚ not by changes in sodium balance. hyponatremia is primarily due to the intake of water that cannot be excreted hypernatremia is primarily due to the loss of water that has not been replaced hypovolemia represents the loss of sodium and water edema

Dehydration Sci/241 Abbe Breiter-Fineberg 4/1/2012 Passing out‚ lethargy‚ constipation‚ dry mouth and even dry eyes are very few symptoms in the long list of signs to tell us that we are dehydrated. Being dehydrated is potentially very bad and if not taken care of a person can end up in the hospital or even dying. Many things can cause dehydration including drinking too much alcohol or simply not drinking enough water. Without ample amounts of water our bodies cannot function correctly‚

the body are closely linked4. The polar nature of water allows electrolytes such as sodium ions to dissolve. The level of sodium within the body affects the amount of water in and around body cells. The body gets sodium from food and drink‚ and loses it in sweat and urine. Sodium plays an important role in water balance and is required to draw water through plasma membrane of body cells. This is because sodium and water move simultaneously‚ maintaining equilibrium of water and electrolytes across

point. Muscle Cell stimulated by Acetylcholine: A motor neuron releases Acetylcholine which diffuses toward the muscle cell across the neuromuscular junction. As the Acetylcholine binds to a receptor on the muscle cell membrane‚ it signals the sodium leak channel to open. This causes a localized depolarization to occur. Soon after this causes the Na+ voltage gated channels to open spreading a wave of depolarization across the membrane and cell.le Cell at rest: As the muscle cell is at rest

Inside the test tube the students put the reagents used for calibration to determine the heat capacity of the calorimeter. These reagents are: sodium hydroxide and HCl. Then the students measure the temperature with 15 seconds intervals. The students made two trials and determine the change in temperature which is needed for the calculations. After the calibration‚ the students
