This scene is broken into 4 sections‚ within it there are 3 characters; Donna‚ Rodney and Melissa-Anne. The first section of the scene was solely Donna explaining what was going on and the current situation of the party. The next section starred Melissa-Anne and Rodney; this was when they were waiting for Donna to pick them up‚ they were in Rodney’s bedroom. The following section was again of Donna and she was explaining to the audience that she had realized what was actually going on and also she

of solutions and test their pH. Due to materials available pH strips were the only testing tools available. A table is setup to compare the strip color to its pH level. Four known solutions including bleach‚ lemon juice‚ soda‚ and baking soda were used. There was also an unknown solution in which the pH level was used to determine which solution it was. The pH scale is 1-14‚ a pH of 7 is neutral‚ less than 7 is acidic‚ and greater than 7 is acidic. Materials: * pH strips * 20 test tubes
Premium PH indicator
A pH meter is an electronic instrument used to measure the pH (acidity or alkalinity) of a liquid (though special probes are sometimes used to measure the pH of semi-solid substances). A typical pH meter consists of a special measuring probe (a glass electrode) connected to an electronic meter that measures and displays the pH reading. The probe The pH probe measures pH as the activity of hydrogen ions surrounding a thin-walled glass bulb at its tip. The probe produces a small voltage (about 0

analyzing pH it measures for the acidity or basicity of a solution. pH levels vary depending on the solution. The more acidic solutions would be juices and vinegar and cleaning materials would be basic. You can determine the purpose of solutions based on their acidity and basicity. We measure the pH of solutions on a scale with levels from 1-14. These levels may change if other solutions are added‚ we can tell what the pH will be based on its colour. Solutions called buffers change the pH levels of
Premium Milk Acid PH
pH pH means Power of Hydrogen or Potential of Hydrogen. pH is a scale of acidity from 0 to 14. It tells how acidic or alkaline a substance is. More acidic solutions have lower pH. More alkaline solutions have higher pH. Substances which are not acidic or alkaline i.e neutral usually have a pH of around 7. Acids have a pH less than 7. Alkalis have a pH greater than 7. There are a lot of ways for finding the pH of something. One way is to use litmus paper. The pH paper is able to tell how strong

Red Cabbage Indicator Experiment Aim: The aim of our investigation was to identify and understand how different chemicals (Acids‚ alkalis and neutral) react and experience a change in colour due of this. Introduction: The red cabbage indicator shows how a usual household product such as red cabbage can make a suitable indicator and be able find out if a chemical is either and acid‚ alkali or neutral. Acids are a chemical that reacts with an alkali neutralising it producing water

Introduction When using different methods to measure pH levels there are some tools that can be useful. Some more than others but by putting into action the different methods it may determine which tools will work best and give the best results when testing the pH within a solution. The pH‚ which stands for the proportion of hydrogen ions in a solution‚ could be acidic (acidosis)‚ neutral or basic (alkaline). The pH scale goes from numbers 1 through 14. A pH of 7 is neutral; meaning the amount of hydrogen

The youth are engaged in vegetable production of which cabbage cultivation predominates (MOFA‚ 2001). Cabbage (Brassica oleracea var capitata) is a temperate vegetable crop which has become very popular in tropical Africa. Its origin and centre of differentiation is thought to be in the west of the Mediterranean basin or in

Animosity Between Blanche and Stanley In the play A Streetcar Named Desire‚ written by Tennessee Williams‚ two of the main characters Blanche and Stanley create chaos within the household. The chaos results in tension‚ which is clearly noticeable from the very beginning of the play. This tension affects others around them‚ the main effect being on Stella (Stanley’s Wife).
