Universal Indicator Solution: Green to Red Properties of Alkalis 1. Alkalis have a soapy feeling and a bitter taste. 2. Alkaline solutions conduct electricity. (Electrolytes) 3. Alkalis change the colour of indicators. Litmus Paper: Red to Blue Methyl Orange Solution: Orange ...
Active metals react with acids to Produce H2 Active metals generally Do not react with bases Both strong acids and bases will conduct electricity when Dissolved in a solution Acids turn litmus paper Blue to red Bases turn litmus paper Red to Blue ...
A base turns orange litmus red. A base turns yellow litmus blue. A Which statement explains why there is a "fizzing" effect during this reaction? The reaction produces convection currents. The reaction causes 2NaCl to boil off. The reaction causes boiling in solution. ...
Acids in water solutions exhibit the following common properties: they taste sour; turnlitmuspaper red; and react with certain metals, such as zinc, to yield hydrogen gas. Bases in water solutions exhibit these common properties: they taste bitter; turn litmus paper blue; and feel slippery. Whe...
Properties of bases React with acids to form water and a salt. Taste bitter. Feel slippery (don’t try this either). Can be strong or weak electrolytes. Change indicators (red litmus turns blue). Names and Formulas of Acids An acid is a chemical that produces hydrogen ions (H1+) when ...
Household bleach is a common base. Bases also turn litmus paper blue. Acids and bases have different physical properties 1. Acids are also corrosive and change litmus paper to red. Effects Changes in pH in the body lead to physical changes. When your body has too much carbon dioxide, the ...
