gives a yellow precipitate with Pb2+: Pb2+ (aq) + CrO42-(aq) → PbCrO4(s) (5) Yellow The other two insoluble chlorides‚ AgCl and Hg2Cl2‚ can be separated by adding aqueous ammonia. Silver chloride dissolves‚ forming the complex ion Ag (NH3)2+: AgCl(s) + 2 NH3 (aq) → Ag (NH3)2+(aq) + Cl-(aq) (6) Ammonia also reacts with Hg2Cl2 via a rather unusual oxidation-reduction reaction. The products include finely divided metallic mercury‚ which is black‚ and a compound of formula HgNH2Cl‚

INTRODUCTION A seed is a fertilized ovule that contains an embryo and transforms it into a new plant through the process of germination. Seeds remain inactive until conditions are right for germination. All seeds need water‚ oxygen‚ and proper temperature in order to germinate. However‚ some seeds require full light or darkness to germinate. According to Holm (1996) seeds have chemical inhibitors that prevent germination. A seed will not grow unless those inhibitors are destroyed by things like

The researchers set a five point scale to determine the characteristics and properties of Paper Radish. The points from the respondents answer to each item over a five point scale are represented as follows: WEIGHTED MEAN SCALE VERBAL INTERPRETATION

The Radish seeds were planted in a pot‚ which contained soil from the garden and cow manure. The Radish was placed in an area similar to the black bean plant and watered daily. According to Yates Expert (n.d.‚ para. 3) radish plants like moist soil and by watering the plant in the evening this helped stop the soil from being dried out from the summer weather. By day eight the radish plant had germinated with more than one seed breaking through the soil. However‚ regular observations showed that

Abstract The purpose of this lab was to see if radiation has an effect on the cultivated radish seeds that we used. From the observed data that we collected‚ we were able to conclude that when seeds are exposed to radiation‚ it affects how they grow‚ if there is any growth at all. Introduction Radiation is an important environmental abiotic factor for plants‚ and one small section of the electromagnetic radiation spectrum‚ is called the Photosynthetically Active Radiation (PAR)‚ provides

Titration Analysis of Vinegar Student: Araik Movessian Grade: 12 Course: SCH4U Teacher: Tijana Knezovic Purpose and Introduction: In this experiment the question of “what is the molar concentration of acetic acid in a sample of vinegar?” was answered via titration using a standard solution of sodium hydroxide‚ NaOH(aq). In this investigation‚ students are to act as quality control chemists. Their purpose is to test the acetic acid concentration of the vinegar to discover whether it

The Ammonia Fountain Experiment To set the ammonia fountain experiment up I made sure I had all the materials the lab required me to have which was: a Florence Flask‚ a 600 mL beaker‚ a Mohr pipet‚ distilled and tap water‚ a polyethylene wash bottle‚ a phenolphthalein indicator‚ concentrated ammonium hydroxide‚ sand‚ a heating mantle‚ a ring stand‚ clamps‚ a two-hole rubber stopper‚ one hole rubber stopper‚ and a medicine dropper. I then filled my beaker three fourths of the way up with tap water

Radish and Collard lab Intro Purpose: To see if the population density affect the growth (mass) and germination of individuals of two species growing alone and in mixed species groups. Hypothesis: If planted like treatment 1 (8 collards) and 4 (8 radish) then it will have a higher mass and a greater germination percentage. If the plant is planted with a smaller population density and has intraspecific competition then the radish and collard will have higher germination percentages and mass averages
