The pH Scale is a scale made to show how acidic or alkaline a substance is. The pH of something is measured with pH paper which can vary from wide range paper‚ which covers all ph’s‚ but is not as accurate at some others. There are pH papers that get very specific that can have a range such as 2 or 3 and get much more precise. The neutral on the scale is 7. Anything that is below 7 is considered acidic and anything above 7 is considered alkaline. Acidic substances contain more H+ than OH-. H+

compounds that generally have opposite characteristics. They have there own unique traits‚ acids taste sour‚ turn litmus red while bases taste bitter and turn litmus blue. The term pH relates to measuring the acidity or alkalinity of a solution‚ such as vinegar‚ or even a damp substance like soul. The neutral pH is 7‚ which is essentially water‚ with lower numbers indicating acidity and higher numbers indicating alkalinity. Hydronium ions (H3O+) are formed when water molecules (H2O) bond with

Purpose: The purpose of this lab was to test how objects slightly acidic or slightly basic will affect the way catalase‚ the enzyme tested‚ denatures‚ or breaks down. Hypothesis: If the potato is acidic‚ it will react with the H2O2 more than it will with the raw‚ plain potato because the acid will denature the enzyme faster. The manipulated/independent variable is the raw‚ plain potato while the responding/dependent variable is the other types of potatoes used in the experiment. Materials:

Body Paragraph What is the history of Major scale? At this time young musician people and children don’t know about this. They didn’t pay attention about history. But this story is very interesting and instructive. And all musician people should know this. ‘In ancient Greece‚ Pythagoras is attributed with using the prime intervals of the octave‚ the P5 and the P4 to break the octave into smaller harmonious intervals. Pythagorean tuning influenced music in the middle ages and Renaissance periods

To what extent do you consider Measure for Measure to be a problem play? Measure for Measure has been deemed as a ‘problem play’ due to ‘lacking humanity’ and the drastic and uneven ‘emotion and language’ throughout the play. Because of this‚ the play is constantly being addressed as ‘problematic’ by critics like Swinburne who describes the play as being ‘indefinable’ and ‘unclassifiable’. The term problem play was first made current by F.S. Boas who was the critique of Shakespeare and his Predecessors

Binet-Simon’s scale has been in use since 1905‚ when it was first introduced to the general public‚ and the scale has experienced multiple changes since the first day. The question is‚ do IQ-test really measures person’s intelligence? According to Howard Gardner’s article “Human Intelligence Isn’t What We Think It Is”‚ humans are multi-intelligence beings. So‚ IQ-test merely cannot provide an accurate representation of an individual’s intelligence level‚ rather IQ-tests generally measure only two forms

IB Biology Sheran Gu Meghan Lena Nov. 15th Influence of pH on Enzyme Activities How does the pH of solution influence the speed of enzyme activities? Enzymes are protein catalysts and chemical that speed up chemical reaction without being involved in the reaction. They are involved in the human digestive system to help people digest food more efficient. Food are substrates to be break down and absorb through the digestive system in the body. Substrate is a molecule that bond with the active site

Types of Measurement Scales Marc Waters MKT/441 June 9‚ 2014 Cyndie Shadow Types of Measurement Scales Introduction For this week’s assignment‚ students are to select four types of types of measurement increasing order of sophistication; they are Nominal‚ Ordinal‚ Interval‚ and Ratio. These are categories in which numbers are grouped. This paper will also demonstrate how they can be effective in surveys or questionnaires. Nominal The number we assign to some object‚ idea‚ or behavior is
