How can one remedy the effect of pH CHANGE due to sterilization?
The effect of pH change due to sterilization is that it cold altered the media
What colour does litmus paper change when pH is neutral?
there natural color it did not change their color
Why does pH make beetroot colour fade?
The color change from red to yellow in the range of pH 10,8-11,2.
What colour does pH paper turn in neutral soloutions?
A moist litmus paper does not change its colour in neutral solutions.
What do we call substances that change colour depending on the pH of the solution they are?
yes well you dont have to pay at all
How do plants like morning glory or hydrangea act as indicators of the soils pH level?
they change colour on reaction to soil pH
What colour will sodium carbonate change pH paper?
Blue

How can pH decrease the shelf life of food?
A chemical change in pH can result in the colour change, browning and loss of nutrients of food.

What is the only sure sign of a chemical change?
Chemical change would cause change in physical quality or thermal value, the most observable quality is colour. It may observed a colour change of reaction but not all reaction had observable change of colour. In that case it will need to add indicator to observe a chemical change. Type of indicator may be different base on the concerned reaction. Indicator chosen may be the type that change colour due to pH or the type that react with contents of product to change colour.
What colour does pH paper turn in neutral soloutions?
A moist litmus paper does not change its colour in neutral solutions.
What changes color at the endpoint of titration?
change in pH, changes the colour (of the indicator)
Can you change the pH of the soil?
First you should universal indicator paper to determine whether or not your soil is an acid or an alkali, then just add whatever you want to change it to. Often with soil it is difficult to change the PH, due to the fact it is the ground around it that is the acid/alkali. If its potted plants youre using then you should check the PH when you but the soil. If its in the ground, it will be very difficult to change.
How does phenolphthalein work?
Phenolphthalein is an indicator that undergoes a colour change from colourless to pink that begins at a pH of 8.0. So in the titration your performing the phenolphthalein will start to change colour at the point when the moles of acid equal the moles of base. Although this colour change occurs at a pH of 8.0 and not at a pH of 7.0 phenolphthalein is commonly used because of the distinctive colour change that occurs. Phenolphthalein is colourless in acids and pink/purple in base. It also turns orange in very strong acids.
Describe how the pH of a solution can be measured using pH paper?
The PH paper soaks up the solution & tests the liquid, the pH paper will then change colour to show what the solution contains. Although if the paper stays the same colour it means the solution is nutral & safe.
