The pH scale measures how acidic or alkaline a substance is. It runs from 0 to 14, with a pH of 7 being neutral, a pH lower than 7 being acidic and a pH higher than 7 being alkaline. The scale is logarithmic, meaning each whole pH value below 7 is ten times more acidic than the next higher value. For example, pH 3 is ten times more acidic than.
Calculate the pH of an aqueous ammonia solution with a hydroxide ion concentration of 2.1 times 10 to the negative third molar. They want us to find the pH, and pH is equal to negative log of the concentration of hydronium ions. But they gave us the concentration of hydroxide ions. So we need something that relates H three O plus to OH minus. This is the equation we talked about in an earlier.
A scale of 1: 100 000 means that the real distance is 100 000 times the length of 1 unit on the map or drawing. Example 14. Write the scale 1 cm to 1 m in ratio form. Solution: Example 15. Simplify the scale 5 mm: 1 m. Solution: Example 16. Simplify the scale 5 cm: 2 km. Solution: Calculating the Actual Distance using the Scale.
The structural calculations included here are for the analysis and design of primary structural system. The attachment of non- structural elements is the responsibility of the architect or designer, unless specifically shown otherwise. The Engineer assumes no responsibility for work not a part of these calculations. When structural observation or field investigation the Engineer is required.
